FIG. 2 shows a flowchart of processing mainly relating to the screen table analysis unit 12.

First, when the process for displaying one screen is started, a command for displaying one screen is fetched from the screen table 11 (S101). Screen table analysis unit 12
Parses the command retrieved.

Here, the command is "STRING command".
If it is determined to be (first character display command) (S
102), analyzing the character display subcommand,
Each data such as color and display position is taken out and the character display information is stored in the display buffer 31 (S103). When it is determined that the command is the "PICTURE command" (first graphic display command) (S105), the graphic display subcommand is analyzed to extract each data such as the graphic type, color, and display position, The graphic display information is stored in the display buffer 31 (S107). The screen display unit 32 displays the contents of the display buffer 31 stored by the analysis result of the character display command or the graphic display command (S109).

When it is determined that the command is "L_STRING" (second character display command) (S11
1), the command, the matching condition, and the character display subcommand are added to the level operation buffer 13 (S113). When it is determined that the command is “L_PICTURE” (second graphic display command) (S115), the command, the matching condition, the graphic display subcommand, etc. are sent to the level operation buffer 13
(S117). Also, the command is "WIN _
If it is determined to be "KEY" (key processing command) (S
119), a command, coordinates, etc. are added to the key operation buffer 14 (S121).

Furthermore, if it is determined that the command is another predetermined command, a flowchart can be added as appropriate so that the predetermined process is executed.

Next, the next command is the screen table 1
It is fetched from 1 (S123), and the repetitive processing is executed until the command indicates the end (for example, "END" command) (S125).

FIG. 3 shows a flowchart of processing mainly concerning the execution unit 15.

After the processing as shown in FIG. 2, the execution section 15 takes out the first command from the level operation buffer 13 (S201). The retrieved command is "L
_PICTURE "(second graphic display command) (S203), it is then determined whether the display condition is satisfied (S205). If the display condition is satisfied, the graphic display subcommand is analyzed, each data such as the type, color, and display position of the graphic is taken out, and the graphic display information is stored in the display buffer 31 (S207). If it is determined that the command is “L_STRING” (second character display command) (S209), then it is determined whether display conditions are satisfied (S211). Execution part 1
When the display condition is satisfied, 5 analyzes the character display subcommand, extracts each data such as the character string, the color, and the display position, and inputs the character display information to the display buffer 31 (S213). Next, the screen display unit 32 displays the contents of the display buffer 31 (S215).
