GetGlobal statement

Syntax: GetGlobal (1, format-statement-label) [,EXCP=statement-label]
Discussion: The GetGlobal statement can be used to retrieve up to 8000 bytes of data, such as user identification information, which was set using SetGlobal. The syntax is similar to an I/O statement using a format to define the layout of the data:

GetGlobal (1,UserInfo) [,EXCP=9000]

UserInfo is a FORMAT statement with a variable list. The first parameter, the 1, indicates that this is user information. We have reserved 0 in its place for system information. In the future, we may use this to return PSTAT-like information. Possible exceptions generated by the call are:

E47 if the first parameter is invalid
E51 if GetGlobal was attempted before SetGlobal was done

UserInfo: FORMAT Name$;Group$;Privileges$
