Global Variable Update by Another Job

1. Enter the job scheduling definition for IDJOB9 and do the following:
   1. Add the following SET VAR statements:

      SET VAR   %%\VAR1=XXX
SET VAR   %%..\VAR2=YYY
SET VAR   %%..\IDJOB8\VAR1=ZZZ

   2. Delete the DO SHOUT statements
   3. Delete the ON STEP / CODES values.
   4. Exit the job scheduling definition.

   The job scheduling definition for job IDJOB9 will now update the values for the Global variables previously defined by IDJOB8.

2. Enter the job scheduling definition for job IDJOB8 and delete the SET VAR statements. Then exit the job scheduling definition.
3. Order job IDJOB9.
4. Once job IDJOB9 has ended, order job IDJOB8.

   You should anticipate the following results of these successive job runs.

   • The SET VAR statements in job IDJOB9 have updated the Global variables with the new values.
   • Because the SET VAR statements were removed from job IDJOB8, this job should not have changed the values that were newly set by IDJOB9.
   • Therefore, you can expect that the JCL of job IDJOB8 used the new values set by IDJOB9.
5. Check the sysout of job IDJOB8. The following comments should appear in the sysout:

   //* VAR1 FROM JOB JOB8 EQUALS ZZZ

   //* VAR2 FROM GROUP GRP3 EQUALS YYY

   //* VAR1 FROM JOB JOB9 EQUALS XXX

   The above values clearly indicate that Global variables can be globally updated.
