The command modify can be used to change any of the fields defined in a job definition. Any of the field parameters discussed under the CREATE command can be changed using MODIFY. MODIFY cannot be used to make changes to the lists of commands, prerequisites, or initiates in a job definition.
The command format is:
C:\> schedule modify job_name /qualifiers
The following example illustrates a case where the job needs to be modified so that it runs on the last working day of the month. In order to change the flag settings so that the job will submit on the last day of the standard month, enter:
C:\> schedule modify/job updt_gl3 /resch=(calendar:standard,named:month_end)
To make it so that the job runs after the close of working hours on the last day of the month, change the submit time to 9:00 pm (21:00) with:
C:\> schedule modify/job updt_gl3/resch=time_of_day:21:00
