The target instruction column 21 stores the format of an input / output routine that can be transferred from the outside. Depending on the instruction format transferred from the outside, for example, a description format such as an assembler language or a C language may be used, or it may be described simply by an encoded bit example.

FIG. 3 shows an example of the contents of the screen command comparison table 6.

Referring to FIG. 3, the target instruction column 21 stores an instruction pattern for character-based screen access in the conventional description format. "DISPLAY" in the command field indicates the contents of the character-based screen identified by the screen name "scrid" from the position specified by the parameter x indicating the line position on the screen and the parameter y indicating the column position on the screen. It is an instruction to instruct the display unit to display.

The parameter "x" is "DISPLAY".
By the command, the character-based screen name "scri
This is a parameter indicating the line position for displaying the contents of "d".
The parameter “y” is a parameter indicating the column position for displaying the content of the character-based screen name “scrid” by the “DISPLAY” command.

The screen name "scrid" is "DISPLA
This is an identifier for identifying the contents of the character-based screen displayed on the display unit by the "Y" command.

Referring again to FIG. 2, the conversion rule column 22 is
When the input / output routine corresponding to the target instruction column 21 is stored, a description describing how to convert to the description format of a new input / output routine is stored. This description format depends on the transfer format when returning to the outside, and may be a description format such as assembler language or C language, or may be simply an encoded bit string. Also,
It may be described in a format with a constraint condition that changes the operation depending on the description format condition of the input / output routine.

Referring to FIG. 3, in the conversion description field 22, a command pattern for newly accessing the screen based on the graphics is stored. In the conversion description column 22, "x
x = 16 * x ”is a command“ Tx− ”that displays a screen in a graphic base by multiplying the constant“ 16 ”to convert the line position parameter“ x ”in the character base into the bit position on the X coordinate axis. It indicates that the data is stored in the parameter “xx” used as the parameter of “send”.

"Yy = 24 * y" is a command for displaying the screen on a graphic basis by multiplying the constant "24" in order to convert the column position parameter "y" in the character base into the bit position on the Y coordinate axis. It indicates that the data is stored in the parameter “yy” used as the parameter of “Tx-send”.

"New-script = search (s
"crid)" is a function "search" that takes a graphic-based screen name that replaces the already registered character-based screen name "scrid", and an instruction "displays the screen with the acquired screen name. It indicates that the data is stored in the parameter “new-script” used as the parameter of “Tx-send”.

"Tx-send" (xx, yy, new
-Scrid) is the screen name "new-scr" from the position specified by the parameter "xx" indicating the position on the X coordinate axis on the screen and the parameter "yy" indicating the position on the Y coordinate axis.
It shows execution of a command "Tx-send" for displaying the screen on a graphic basis that instructs the display unit to display the contents of the screen identified by "id".

Next, the operation of the embodiment of the present invention will be described in detail with reference to the drawings.
