Hi Les,

I had loads of problems using named pipes using a Borland C/C++
compiler. The run-time library seemed to check for a _file_ called
\PIPE\Mypipe and when unable to find it, attempted to create it; when
this failed the fopen() would fail.

Coding directly to the DosOpen(), etc., API worked. Also, switching to
C Set ++ worked using fopen(), etc.

The fact that TYPE and MORE can handle the pipe indicates that it is
being created correctly. Since these use the raw API, I suspect your
compiler's run-time library is not handling it correctly, a la Borland.

Which language, compiler and version/release are you using?

Regards

Dave
