DarwinGroupListMBS.CurrentEffectiveUserID as Integer

dim l as new DarwinGroupListMBS
MsgBox str(l.CurrentEffectiveUserID)

The real user ID is that of the user who has invoked the program. As the effective user ID gives the process additional permissions during execution of 'set-user-ID' mode processes, getuid() is used to determine the real-user-id of the calling process.

DarwinGroupListMBS.CurrentGroupID as Integer

dim l as new DarwinGroupListMBS
MsgBox "CurrentGroupID: "+str(l.CurrentGroupID)

The real group ID is specified at login time.
