If a command runs at the DOS prompt, I expect it to run when shelled from Perl. Is this asking too much?

Sadly, the answer in some cases is Yes. I'm not sure of why this is.

I've been able to work around this in most cases by doing one of 

  1. system("map > temp");
open(M, "<temp") or die ...;
@dmap=<M>;
close(M);

  2. open(M, "map|") or die ...;
@dmap=<M>;
close(M);

How does the latter case differ from backticks? Perhaps someone with Deep Knowledge will educate us.

(I'm assuming that you have a DOS executable named "map". I don't, but I've run into this problem with other programs.)
