I met the 20-files limit. That is, somewhere in a DOS programmers manual
appears:
When MS-DOS creates or opens a file, it assigns the first
available handle. A program can have 20 open handles; this
includes the five predefined handles, so a program can
typically open 15 extra files. [...]
but I want to open more files!
Has anyone reached this limit and found a way to overtake it ?
I know 'files' and 'fcbs' keywords from config.sys but that won't let
you go past 20.
All kind of info is welcome! (I mean, usefull one ;-)
Thanks in advance.

"I've had nothing yet",Alice replied in an
offended tone, "so I can't take more."

Even better, he said he was putting the source and executable code into the public domain (but, I assume, keeping the copyrights). Best of all, though, is that he said he would send fully documented source and executable to anyone who asked for it and sent him a blank, formatted 5 1/4" diskette and an addressed, postage-paid return mailer. I thought this was so nice of him that I sent mine in a week or so aog (things get backed up). So, I expect that I will be getting this before too long. When I do, if it is not a violation of his rights, I will post the source code on the net (comp.sources.ibm.pc). If you can't wait, here is the address he gave in _Infoworld_ (but don't flood the guy, if you *can* wait): Gibson Research Steve's TSR Offer Box 6024 Irvine, CA 92716 Remember, include a formatted diskette and an addressed, postage-paid return mailer for it. It sounds like a great deal for those of us who need more than 20 files. GKB
