Hi tholen@antispam.ham

It does seem to work for me (YMMV). Here's the code, compile line and
output. If you give me (by email reply to this address) an email
address I will forward relevant excerpts from the ifc7.1 documentation to
you, but I'm reluctant to post them to the group. There's nothing very
exciting in the docs for this anyway though.

My test code and output:

program t
character(20) :: output
call getarg(0,output) !This should return code name.
print*, output
call getarg(1,output) !This should return first argument.
print*, output
end program t

bash$ ifc -V
Intel(R) Fortran Compiler for 32-bit applications, Version 7.1

bash$ ifc t.f90 -Vaxlib
   program T

14 Lines Compiled
bash$ ./a.out 123
 ./a.out
 123
bash$

I hope that helps you.

Yours,
Andy

PS: There was a debate about capital 'V' for Vaxlib... Yes it is required,
and I do get a warning if it's ommited - see below. By the way, for
Windows, the documentation suggests the -Vaxlib should be replaced by the
/4Yportlib switch, but I don't use Windows.

bash$ ifc t.f90 -vaxlib
ifc: Command line warning: ignoring option '-v'; no argument required
   program T
