[fpc-pascal] Any command line interpreters for Free Pascal?

[Roland Schäfer]

I get the impression that you want to use Pascal for something it wasn't
designed for. Even if you can find some kind of solution, it will
probably be a bad hack. But that question is probably for fpc-other.

So anyway, the only solution I can think of is to automatically comment
out the shebang by calling sed or something from your makefile if you
"compile as a program". (As fas as I understand, this is exactly
equivalent to what instantfpc does in the background, since it is NOT an
interpreter. So what you do is in fact make a lot of fuss about two
different ways of generating and running exactly the same executable.)
You can even remove the comment after compilation again. This is as bad
style as using the old #if 0 construction for debug code in C, though.

Good look,
Roland
