Re: re-reading records in CL (not after EOF!)

I've used other than *START when I know where I want to begin, as in 
processing output of spooled files - why read the header? Of course, you're 
stuck with version changes by IBM hurting you.

In the loop you describe, did you get the CPF0864? Will the RCLRSC work if 
you do?
