Once again a big thank you for this information.
issue came up again. This time it was a Microsoft Update on my office computer. I discovered that my old LATEX.VCS file had such a command. So, when I tried to launch my latex compiler from Vedit, I got the error message:
CAN NOT SHELL OUT, ERROR 5.
My systems person told me that this Microsoft Update, eliminated 16 bit API programs. So, your explanation was great.
Then I found out that Christian and Fritz have also updated LATEX.VCS. Needless to say, the updated file works like a charm.
Incidentally, is there a direct way of finding out that
MSDOS95C.PIF makes a 16 bit function call ?
