 I don't think unit Dos is needed here, BTW.

 Well, I've probably found the reason now. First, it isn't a problem 
with MAKE - a simple program with just one "Exec ('maketest.exe', 
'')" line shows the same behaviour. In fact, it seems to be a bug in 
our ParamStr (0) implementation. The problem is, that some command 
shells (e.g. 4os2 or FC/2 - not a real shell, right, but used that 
way) expand the called program to full path automatically; that's why 
we thought it works. Just try running your maketest.exe under plain 
CMD.EXE, you'll probably see the same result as with make. We'll have 
to fix it.
 Another valuable bug report - keep them coming. ;-)
