In my test scenario of:

        callci showme | FDTEST | cat -

FDTEST's input pipe should be closing rather quickly after the last line of
showme output is read, but a "while CCODE = CCE" loop cycles infinitely with
CCE/length=0.

I'll re-test the input pipe case with a big pause in the middle of whatever
is feeding the pipe to see if there's a hang or whether it's CCE/length=0.

My command of computer languages frequently exceeds my command of the English
language.  ;-)

What I meant to say is:

Summary: it is possible now to write MPE CGI programs under 5.5 using READX
and PRINT without PM.

This actually works as expected (well, there's that CCE/length=0 issue I need
to look at further...).
