When using TC to create a module or executable, the RTL requires the C
library to link.

So you so not need a C language module, or special CALL.

As per your example above.

01 FIELDX.
   05 FIELDX-CMD X(25) value 'ls -la'
   05 FIELDX-END X     value x'00'.
...
CALL "system" USING FIELDX

Hint when calling C functions.
Case is important and any C string parameters should be NULL terminated.

Hope this helps.
