You can call any C library function.

To achieve a 'system' call try using some thing like the following example.

Example:
...
01 parm1.
   05 parm1-value1 pic x(20).
   05 parm1-value2 pic x(01) value x"00".
...
move "ls -l *.cpy" to parm1-value1.
CALL 'system' USING parm1.

Note that since you a calling a C function, the string must be NULL
terminated.
