Arguments

A variable up to 254 characters long. The PUTCM subroutine places the contents of this variable into the process common area. (a)

Discussion

The PUTCM subroutine calls the OpenVMS system service LIB$PUT_COMMON with the specified argument, thereby enabling your program to transfer data using a common area.

The PUTCM subroutine, in conjunction with the GETCM 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.
