Re: scanning for a hex value in RPGIV

Thanks Mike.

I don't know why my scan doesn't work either, but I'm not going to agonize
over it any more. I'll figure it out eventually.

I've found some other weird things that have happened on this V4R5 system
that no one else ever seems to come across, so I don't know if I've got
gremlins or what. Ran into some funky CGI errors the other day that even
Brad Stone hadn't seen before.

I'm going to order and load the latest cume and see if that fixes some of my
problems.  However, the problem with scan is likely with my logic or
assumptions, and not with RPG or OS/400. Since scanning for a hex value
worked for you (and others) it should also work for me, so I'll keep at it.

Thanks all for your responses!
