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.
See also
- The setGlobal method, in the Subsystem class, performs a function identical to the $setg_subsys function. That is, the following two statements are identical:
%(subsystem):setGlobal('PHLEGMATIC', 'STOLID') %setg_subsys('PHLEGMATIC', 'STOLID')
