JOBSCAN, JCLCHECK or some equivalent could not beat JOL because it normally did not cause any failures. It was a product that was ahead of its time and all it really needed to succeed was a larger support organisation and better marketing, which is the minimum that any product requires to be successful, as any of us who have put a product onto the market will confirm. I have not examined the current free release of JOL, but I would expect similar error free results from its execution. I confess that I have a slight bias toward JOL as I started learning assembler on shift, using the JOL assembler as a model, in the very early seventies and always recall the comment that read. "I should never get here, but in case I do I better do something about it". That reminds me of MVS error handling. I will respond to the JCL generation comment "or the total lack of JCL" when I have had a chance to test the current version of JOL.
