System Generation Compiler › Execution Modes › Online System Generation › Online Session

Online Session

An online session begins when you invoke the system generation compiler using the task code defined to the host TP monitor. The installation default task code for the system generation compiler is SYSGEN.

The screen displayed by the compiler is formatted for use with the online text editor. The top line identifies the compiler, as shown next. The remainder of the screen is used for input and output.

                SYSGEN 17.0  PAGE 1 LINE 1  DICT=CORPDICT   EMPTY  cv-name

After invoking the compiler, you enter system generation statements in the input/output area of the screen:

• Enter the SIGNON statement if necessary (as described under SIGNON Statement).
• Enter the SET OPTIONS statement, if appropriate, to establish processing options for the session.
• Enter ADD, MODIFY, DELETE, DISPLAY, and PUNCH statements and compiler-directive statements as needed to define and generate DC/UCF systems. Statements must be entered in accordance with the guidelines presented under Coding Considerations.

The following sample screen shows system generation statements that have been entered by the user but not yet processed by the compiler:

                  SYSGEN 17.0   PAGE 1 LINE 1  DICT=CORPDICT    EMPTY   cv-name
 modify system 9.
 display all tasks with none.
 add task txt078 invokes program pxt078.
 add task txt079 invokes program pxt079.

The following sample screen shows the compiler response to the statements shown on the previous screen. Because the ECHO option of the SET OPTIONS statement is in effect, the compiler redisplays the input lines along with the output. The SET OPTIONS statement is described in SET OPTIONS Statement.

                      SYSGEN 17.0 NO ERRORS   DICT=CORPDICT     1/12   cv-name
 MODIFY SYSTEM 9.
 DISPLAY ALL TASKS WITH NONE.

 ADD TASK TXT078 INVOKES PROGRAM PXT078.
 ADD TASK TXT079 INVOKES PROGRAM PXT079.

To terminate an online compiler session:

1. Enter the SIGNOFF statement in the input/output area.
2. Press the CLEAR key to return to the host TP monitor or to TCF (if executing under TCF).

Alternatively, you can use the top-line command END to terminate an online compiler session. Top-line commands are described in the CA IDMS Common Facilities Guide.
