SetGlobal (System subroutine)

Set a system-wide global (System class)

The SetGlobal shared subroutine sets a System global.

Syntax

%(System):SetGlobal( name, value)

Syntax terms

%(System)	The class name in parentheses denotes a shared method. SetGlobal can also be invoked via a System 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.
• Like $Setg_Sys, the SetGlobal method 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.

Examples

1. The following statement sets the system global called CHOLERIC:

   %(system):setGlobal('CHOLERIC', 'ANGRY')

• The setGlobal method, in the System class, performs a function identical to the $setg_sys function. That is, the following two statements are identical:

  %(system):setGlobal('PHLEGMATIC', 'STOLID') %setg_sys('PHLEGMATIC', 'STOLID')
