CEEGPID callable service

CEEGPID retrieves the Language Environment version ID and the platform ID. The version ID returned by CEEGPID can be tested to determine if you can use new or extended functions that are available in a particular release of Language Environment. For example, POSIX, ENVAR, and CEE3CIB are functions available in Release 3. Before using any of these functions, you can test the Language Environment version to make sure you are running on the release of Language Environment that supports them.
