Changing a job description
You can use the character-based interface, the Work With Job Description (WRKJOBD) command, or the Change Job Description (CHGJOBD) command to change job descriptions. Command: Change Job Description (CHGJOBD) All jobs that are started after the job description is changed that use that job description are affected. If you have changed a job parameter to something different than the what is specified in the job description, that parameter will not be affected.
