Set a subsystem global (Subsystem class)

The SetGlobal shared subroutine sets a Subsystem global.

Syntax

%(Subsystem):SetGlobal( name, value)

Syntax terms

%(Subsystem) The class name in parentheses denotes a shared method. SetGlobal can also be invoked via a Subsystem object variable, which may be null.
name A string that identifies the global to be set.
value A string that identifies the new value for the global.

Usage notes

  • All errors result in request cancellation.
  • It is not an error to set a global that is not set.
  • The Subsystem class SetGlobal sets the global for the current subsystem context (indicated by Context).
  • Like $Setg_Subsys, SetGlobal momentarily turns off multi-processing, so should not be used heavily in an MP/204 environment. SetString does not suffer this limitation and should be used in these situations.
