Load the contents of a common area into a variable




VSupported on OpenVMS
xcall GETCM(variable)



A variable up to 254 characters long that is loaded with the current contents of the process common area. (a)


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.
