Definitely. JES and the system utilities that you use are always "up-to-date". JCL-checkers never seem to be. TYPRUN=SCAN or toss it in with a known error. Forget the JCL-checker altogether, you'll spend time either chasing your tail or ignoring actual problems, so why bother?

I have grown to like the JCL checker in our shop because it also reports on data sets that do not exist, security violations that I might commit, and whether or not the job will fail on s806 because I have the wrong STEPLIB. Very valuable information. I can forgive it some synax lapses.
