Program group
An organizational unit of programs in the internal session. There is always a
main program group and it is possible to have several
additional program groups. Each program group has a
main program. Loading
function groups and loading
class pools always leads
to the creation of an additional program group. If, however, using a program that is not a function
group or class pool causes the program to be loaded, it is loaded into the program group of the user. All programs of a program group share the
interface work areas
declared with TABLES,
NODES and COMMON
PART. Within a program group, CALL SCREEN can only be used to call the
screens of the main program.
