ENV
specifies that the named table is visible to all NCL processes executing in the
current environment.
GLOBAL
specifies that the named table is visible to all NCL processes executing in the
current NonStop NET/MASTER MS system.
PROCESS
specifies that the named table is visible to the current NCL process only. This
includes all NCL procedures in the current NCL process.
REGION
specifies that the named table is visible to all NCL processes executing in the
current region. This includes any EXEC, START, or INTCMD NCL processes
in this region and any NCL processes executing in the other opened OCS
window.
NEWEST= n | OLDEST= n
specifies that only the oldest or newest n entries are to be deleted. These operands
are useful for tables that are being used as caches. If neither operand is selected,
all entries in the table are deleted.
Considerations
The &SYS.FDBK system variable is set after a VARTABLE RESET statement,
indicating one of the following results:

Description
0 The table was reset successfully.
16 No table of this name exists in this scope.
Changes to a vartable using SCOPE=CACHED are carried out simultaneously in
all processes that contain the vartable as a cached copy. Such changes are applied
to the local cache copy, and also to the global copy. Return to the process is
delayed until the changes have been carried out. If you specify SCOPE=GLOBAL,
any changes are applied only to the global copy of the vartable prior to returning
to the process; consequently, there may be some delay before the local copy of the
table is updated.
As a result of the updating method for cached copies of global vartables, processes
that update a cached global vartable can be guaranteed a consistent view of that
vartable only if they use SCOPE=CACHED.
