According to Thomas Tan:

I get wierd errors when I try to compile the command line argument example. First it had a problem with the line (ParamStr := ";), so I changed the " to ""

An empty string was meant, so the correct thing would be '', but "" works, too.

Then it said ( cmdline.pas(36) Error: undeclared identifier `Arg_num'" )about the line ( Success := _p_paramstr (arg_num, Str);) I don't know what's wrong.

Change it to `num', then it should work.

The part of the documentation you are referring to is outdated.

The packages `BPcompat' and `BO5', both available from ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/contrib/, contain tested, BP-compatible versions of `ParamCount' and `ParamStr'.

In addition, I am currently working on making those functions built-in.

Hope this helps,

Peter
