Hi Peter,

You are correct.  My test program works the same way under the
different OS's/Compiler.  When I include fflush(stdin), only djgpp
gives a problem. Thus the bug(?) isn't in scanf(), but is in
fflush(stdin).

Looking more carefully at the real code that generated the error, I
discovered that I'd been already been running fflush(stdin) after this
block of code exited (the code was initially developed under SUNOS, and
so I probably had to do this to avoid the problem in the first place).
Hence, any remaining input would be flushed (and is, except under
djgpp).

While I had programmed around the problem by using gets()/sscanf() much
like you suggested, in this part of my application, scanf() is really
much simpler.  For now the best suggestion I received is to clean up by
using scanf("%*[^\n]\n"), which works.

Thanks to all.
