Fortran question

["Padiyath Sreekumaran" <kumar padiyath psi ch>]

Hello,
Iam sorry if I put this question here. Since I have a lot of
Fortran programs(all running still on Tru64 machines)
 which Iam migrating to Linux, I am having the following question:
Iam using a lot of "call system('ls -l')" statement  which execute
different
unix commands inside my program. How can I replace this in Intel or
pgf90 or
some other fortran compilers on Linux? 

Thanks in advance.
Regards,
Kumar
