Hi,
Please feel comfortable asking these questions.

First, realize that what looks like simple code already has a ton of
background code. You are working on linux, not DOS. So including the
CRT unit already messes you up. Using clrscr; invites a lot of runtime
errors, especially from the fp IDE.

A good approach on linux is to use xterm. It is the equivalent of a
DOS CRT, except you can have 50 of them running simultaneously. So you
are already far beyond TurboPascal on DOS. Each xterm, when active,
has read and write called standard input and output. This is where
gentoo is nice, it will open new xterms in your working directory. You
can compile in one xterm, with a great fpc error message system. Then
run in another xterm.

For me, when fpc is properly configured (and IIRC fpc2 did properly
configure when using the RPM) simply typing (at the prompt) fpc
selbsttest_s_25.pp will produce informative error messages or an
executable file. Then on a separate xterm (effectively a separate DOS
computer, but better) type " ./selbsttest_s_25 " .

I have never used the CRT unit. I am working on something similar to
Ken Wright's oCRT unit. But I won't pretend it will work on other than
linux.

If you are working on linux, and using freepascal, you are no
beginner. That is certain.

Rick.
