C$LIST-DIRECTORY The C$LIST-DIRECTORY routine lists the contents of a selected directory. Each operating system has a unique method for performing
this task. C$LIST-DIRECTORY provides a single method that will work for all operating systems.
C$LOCKPID This routine returns the Process ID (PID) of the process holding the lock responsible for the previous file lock or record
locked condition encountered. This library routine works only with the Vision file system and the UNIX platform.
C$MYFILE Returns the filename of the disk file containing the currently executing program.
C$NARG This routine returns the number of parameters passed to the current program.
C$PARAMSIZE This routine returns the number of bytes actually passed by the caller for a particular parameter.

C$RUN ACUCOBOL-GT for Windows supports an alternate method for running other programs. This is through the library routine C$RUN.
This library routine works identically to the SYSTEM library routine, except that the calling program does not wait for the
called program to finish. Instead, both programs run in parallel.
C$SLEEP This routine causes the program to pause in a machine efficient fashion.
C$SYSTEM This routine combines the functionality of "SYSTEM" and "C$RUN". It allows you to run other programs from inside a COBOL application
in a variety of ways.
