Yes, but do not forget that:
1) you are calling C code (i.e. strings must be null terminated)
2) if you are calling a function like system you must use RETURNING
   to get the result.
So your code should look like :
  01 cmd.
    05 filler pic x(30) value "ls -l >temp".
    05 filler pic x value low-value.
  01 status pic s9999 comp.
and
     call "system" using cmd returning status.

See examples of calling C code in test_suite/call_tests/ptest02.cob
and stest9xx.c.
