OF VARIABLE SCREEN SIZE ON
TIIE DISPL~Y OF A TEXT PROCESSOR

5 Tcchnical Field This invention relates to text processing systems, i.e., information processing systems wherein the processing affects the format of the information. It provides such text processing systems with a data 10 processing capability, i.e., processing operations wherein the processing relates to the value of the information.

ackground Art In prior art information processing systems, 15 there has traditionally been a dividing line between rdata proccssing systcms and text or word proccssing systems. The older data processing field developed over the past for-ty years is directed to information processing the primary purpose of which is to affect 20 the value of the information being processed. The processing involves mathematical and other computa-tional operations such as ordering and sorting which affect thc substance or value of the information. In general, data processing is not concerned with format 25 of the information except to the extent necessary to make the information readable or discernible to the opcrator either through a display or a printout.
Otherw;se, form i5 of no consequence.
On thra other halld, itl th~ newer word processil-lg 30 or text processing field which has developed over the past ten years, the vaIue or substance of the infor-mation is of little consequence. Text processing is .~

~L~73973 l concerned with the formatting of alphanumeric data into a format or arrangement suitable for specified printed documents which are to be read and discerned by the public, e~g., letters, textbooks, magazines and newspapers.
Because of these substantial differences in functions, text processing equipment has been in general developed and marketed independent of data processing technology. Most businesses which require both data processing and text processing are likely to have independent systems for each function.
In recent years there has been some information processing equipment available which purports to carry out both data processing and text processing opera-tions. However, such systems involve a processor which upon the loading of operational programming will act as a data processor to the completion of any initiated data processing operations. Alternatively, upon the insertion and change of operational program-ming, the processor may be converted into a word or text processor and perform only text processing operations until their completion. Canadian Patent Application No. 411,110, entitled "A Text Processor Having an Interactive Display Terminal which Alternately Functions as a Data Processing Terminal", S. F. Clements et al, filed on September 9, 1982, and assigned to a common assignee provides an interactive system which is capable of switching from an initiated data processing session to a text processing session before the completion of the data processing session and then to switch back to the data processing session and resume the incomplete data processing operations at the point where the session was switched to text processing. The system in aforesaid Canadian Patent Application No. 411,110 utilizes a text or word processor having an interactive .,~

display terminal for conducting said text processing operations and a data processor for conducting said data processing operations. The system further includes means activated during the data proccssing sessions for operating the text processor as an emulation of an interactive display terminal and means for connecting said emulated display terminal to the data processor so that the emulated display terminal ~unctions as a display terminal for said data processor.
Xn order that a text processor have the capability of functioning as a display terminal for a plurality of data processors it is important for the display of the text processor to be able to emulate a variety of data processor displays so that the operator is in 15 effect utilizing the display terminal as a selected data processing display terminal.

Disclosure of the Invention The system of the present invention provides its capability through the combination of the tex-t proces-20 sor having an interactive display terminal and a dataprocessor. Text processor has means for conducting data processillg sessions ~etween text processing sessions. The present invention further includes means operational during data processing sessions to 25 define selected outer dimensions of a limited area of the (3isplay terminal to correspond to the dimensions of the particular data processing display terminal screen being emulated. In other words, the system is capable of emulating a plurality of different data 30 processing terminals. In emulating this plurality of different display terminals, the system has means for storing in the text processing system data representa-tive of the out]ine~ of a plurality of different data processing display screens to be emulated and a means .

1~'73973 l for selecting one of the plura]ity of stored outllnes to be displayed as the emulated screen.

Best Mode for Carrying Out the Invention In our description of the preferred embodiment for carrying out the present invention, we will utilize hardware which has already been described in the above-mentioned Canadian Patent Application No. 411,110. This hardware is shown in Figs. l and 2.
The system comprises a text processor lO including a display 17. A host data processor ll i~lrs-sl-055 :~73g'73 communicates with text processor 10 over buss 12.
Text processor 10 includes a communications adapter 14 connected to buss 1?. Tn text processor 10, the operator accesses the processor through operator 5 control keys on keyboard 15. The keyboard drives a processor 16. The processor is operably connected into a visual display 17, a diskette 18, and a random access memory 19 through a memory buss 20. A system clock 21 is provided for timing functions wlthin text 10 processor 10. A printer 13 associated with text processor 10 is communicated with over buss 22.
Memory 19 has the means for storing data and for controlling display 17 to display data or printer 13 to print data. Memory 19 includes a number of data 15 areas and function programs for operating with the data input into it through buss 20 from communications adapter I4.
With reference to Fig. 2 which shows the elements o~ memory 19, many of which will be described herein-20 after in greater detail, the data to be displayed is stored in text storage buffer 23. The handling and updating of data stored in text storage buffer 23 is controlled by routine stored within text storage buffer manager block 24.
The displaying of data stored in the text storage buffer 23 on display 17 of Fig. 1 may be done in any conventional manner. The data stored in text storage buffer 23 is sequential data representative of alpha-numeric data. For convenience, such data may be 30 referred to as text character data. In displaying the ch~racters, text character data stored in buffer 23 is communicated to di~play access method 25 throll~h display manager 2~. The data from the display access method 25 is applied to display refresh buffer 27 35 which operates in the conventional manner referred to 3~3 1 above to maintain alphanumeric text data representative of the stored data on visual display screen 17 (Fig.
1). It should be no-ted that display manager 26 serves to store flag and status information as required by the operation of display access method 25.
In accordance with the aforesaid Canadian Patent Application No. 411,110, the system operates as a text processing system wherein the system operates under the control of a internal processor 16 which controls memory 19 shown in detail in Fig. 2 to perform various formatting operations utilizing display 17 and to produce documents on printer 13 in accordance ~ith the operation covered in Canadian Patent Application No. 399,201, filed March 23, 1982, by Dennis G. Busch, entitled "Data Communications System with Receiving Terminal for Varying the Portions of Received Data Being Displayed". Also, system invol~es data proces-sing sessions wherein the host data processor 11 communicates with memory 19 through buss 12 and communications adapter 14 which accesses memory 19 through buss 20. In such a data processing operation, the data from communications adapter enters memory 19 (Fig. 2) Oil buss 20 and is input into communications access method 28 after which the data is input over channel 29 to communications monitor 30. Information from communications monitor 30 is input over channel 31 to text storage buffer manager 24 and the data is input into the text storage buffer 23 over channel 32.
Since the operator controls the processes being described through a keyboard 15 communicating through a processor 16, standard keyboard entry processes should be generally described. As the operator enters each keystroke at the keyboard 15, a corresponding signal is transmitted through channel 42 to processor 16 which enters the keystroke command into memory 19.

In the memory, upon the receipt of a keystroke command, a keystroke routine is called for keystroke service routine block 33 to handle the particular command received. The keystroke command is then processed via channel 34 to text storage buffer manager block 24 which has the capability to control buffer control block 35 to carry out various proccsses with respect to the data stored in text storage buffer 23.
Now using the logic and memory previously described above with respect to Figs. 1 and 2, the operations involved in the present invention will be described with respect to the flow chart of Fig. 3.
The screen size is determined by the host processor 11. Let us assume that the host processor requires a switch in screen size. First, the data interrupt is reccived, st~) 40, Fig. 3. This request comes throu~h the communications adapter in Fig. 1 in the previously described procedure. Communications adapter 14 communicates with memory 19 of Fig. 2 through channel 20 and communications access method 28. Then, the communications access method requests a buffer from buffer pool management unit 43 in Fig. 3. In response, the buffer pool management updates the buffer pool control block 44, step 45, Fig. 3. Next, step 46, Fig. 3, buffer pool management unit 43 provides a communication access method 28 with a particular buffer dcsignation or address in buffer pool block 47.
~ t ~his point, step 48, the communication access m~thocl 28 accesses thc bufEer pool, block 47, over channel 49 and p1aces the data being communicated into the assigned buffer in buffer pool 47.
Now, the communications access method, step 50, updates the communications control block to reflect where in buffer pool 47 the particular data is being ~T9-81-055 ~3~3 stored, i.e., the address. Next, step 51, communi-cations access method passes this address to the communications monitor 30. The communications monitor 30 verifies the data, step 52 by accessing the data in the buffer pool at its address. During this verifi-cation, the monitor in effect verifies that the data fits all of the rules of the communication protocol being used~ Next, step 53, communications monitor 30 updates the communications control block 54 to indicate that the data has ~een verified and is valid. Next, the communications monitor 30 passes the data, step 55, to the text storage buffer manager, unit 24. The data passed to text storage buffer manager contains data indicative of the desired screen size. Thus, in step 56, the text storage buffer manager detects the appropriate screen size, i.e., whether there is a screen size change in the received data and, the text storage buffer manager updates the buffer control block 35, step 57, to indicate the appropriate screen size. The screen size is stored in this buffer control block. Next, step 58, a decision is made in the text storage buffer manager as to the appropriate screen size.
At this point before proceeding any further it will be advantageous to illustrate the various screen sizes involved in this embodiment. For convenlence in illustration, we have selected a system which may produce data processing terminal screen emulations having two screen sizes which we have illustrated in Fig~s. 4 and 5. In Figs. ~ and S, we have shown an outline of a display unit 17 which is the display of the text processor. The display unit contains a display CRT screen, the outline of which is shown at 59 and the various operator controls which are repre-sented by dial 60. In Fig. 4 at 61 we have illustrated .. . ..

39~3 the outline of a first smaller screen data processiny screen size which may be emulated. This screen may contain in the order of about 1920 character spaces.
In Fig. 5 we have shown the outline of a larger screen 62 whieh may be emulated and this may contain in the order of 3440 eharae-ter spaees.
Getting back to decision block 58, a determination as to which of the two screen sizes is to be emulated is macle by deciding whether the screen size is to be greater than 1920 eharaeter spaces. If it is, then, step 63, the text storage buffer manager 24 instructs display manager 26 -to proceed through the display aceess method 25 and display refresh buffer 27 to have the sereen display the large eharaeter screen, i.e~, the one that eontains 3440 eharacters which is shown in Fi~. 5.
On the other hand, if a decision is made in block 58 that the sereen size is not greater than 1920, i.e., the smaller screen size shown in Fig. 4 is to be utilized, then the text storage buffer manager 24 instructs the display manager 26 to display the 1920 eharaeter sereen. In any event whether step 63 or 64 is followed, the display manager in step 65 updates the display manager eontrol bloek 68. Then the display manager 26 will request the display access method 25 to chan(Je to selectecl screen size, step 69.
The display access method 25 proceeding through the clisplay reEresh L)uffer 27 will have the appropriate sereen si~.e utilized, step 67, after which the routine is re~urlled and the data processing session may eommenee or resume utilizing the appropriate screen size.
While the invention has been particularly shown and described with reference to a preferred embodiment it will be understood by those skilled in the art that ~T9-81-055 1:173973 various othcr chan~Jes in form and dctai] may be made without departin~ from the spirit and scope of the invention.
