Discussion
The GETCM subroutine calls the OpenVMS system service LIB$GET_COMMON with the specified argument, thereby enabling your program to transfer data using a common area.
The GETCM subroutine, in conjunction with the PUTCM subroutine, manipulates data within a common area that is maintained by OpenVMS for each process on the system. Because this common area is unique to each process, Synergy programs can use this area as a private “scratch pad” space for communication between programs that will be chained to later.
