Re: link error in linking sample user exit program

The answer to this was put into the release note around Pro*C 1.3.17.0.7, or so. It's not at all intuitively obvious.

There's a problem with Microsoft Link and very large DOS executables. This is related to how much free memory in the lower 640K you have, and the size of the executable generated. rfm & rfmp are small enough that they're happy with whatever you're giving them. If you run MSLink in OS/2, or use SLR Systems' OptLink, this problem goes away. Also, if you load more TSRs this will cause rfm & rfmp to fail this way too.

Yes, it can't open the run file because the disk is full.

This temp file is the culprit. When memory is low, for some reason the linker starts endlessly writing to this file. When the write fails (the disk is full), the linker attempts to open the run file. This fails since there's no free space on the disk. Link displays the error, kills the temp file, freeing up all the space.

Finding this was slow going since it frequently took >24 hrs for the disk to fill. Freeing up disk space doesn't do any good - it just makes the error take longer to show up.

The amount needed was either 500 or 600K to get them all to work under DOS. I forget which one but I remember being surprised by the round figure. I don't know if this has been fixed in a more recent linker version.
