I am using the new "net" release...  There doesn't seem to be
one central cygwin.dll anymore.

-rwxrwxrwx   1 administ Administ     1291 Apr 30 23:58 cc.pl*

> - And after editing?

I edited crash_func.pl and saved it within vim:

-rwxrwxrwx   1 administ Administ     1291 Apr 30 23:58 cc.pl*
-rwx------   1 administ Administ     7202 May  8 23:35 crash_func.pl*
-rwxrwxrwx   1 administ Administ     1695 Mar 27  1999 mag.pl*
-rwxrwxrwx   1 administ Administ      934 Apr 30 23:50 rs.pl*

I try to execute $perl crash_func.pl

and I get

Can't execute /cygdrive/d/util/scripts/crash_func.pl.

I do a chmod 777 and then I can execute...
Like I said in my previous post this could be complete
"pilot error".

I read that in their online docs and that's why I tried the different
"fileformat" settings hoping that would fix it.

I don't use the mouse ( why use vi and a mouse??? :)   ) but I 
compile in some ATL code to drive Visual Studio from vim.    

Thanks for answering...
