I am a newbie AS400 student and am learning from a course. I wrote and compiled a simple control language program. However, when I call the program I get the error "Processing command failure, refer to job log for details." I tried using wrkjoblog and wrkactjob but couldn't find the log I was looking for. Where can I find this log? Also, is the job log my primary tool for troubleshooting a failed program or are there other better options. Course doesn't really seem to cover that. Thanks in advance for your help.
