Editing WoW:API setglobal

{{wowapi|toc=0}}
Set a global variable, from a string.
 setglobal( "globalName", value )

== Deprecation ==
Both [[API_getglobal|getglobal]] and setglobal are deprecated and replaced with the '_G[]' <ref>http://forums.worldofwarcraft.com/thread.html?topicId=25626580975&sid=1</ref> the global table. Their functionality will be removed from the game at a future date.

Replace all references of 'getglobal':
 var = getglobal(varName)       --getglobal deprecated
 var = _G[varName]              --new syntax to get a global

Replace all references of 'setglobal':
 setglobal(otherName, otherVar) --setglobal deprecated
 _G[otherName] = otherVar       --new syntax to set a global

== Parameters ==
=== Arguments ===
:("globalName", value)

:;globalName : String - Name of the global you want to change.
:;value : Any - Value you want to set the global to.

=== Returns ===
:;Always returns nil.

== Example ==
 /script setglobal( "MyVariable", 1234 )

=== Result ===
 MyVariable = 1234

== Details ==
As of the introduction of [[API getfenv|getfenv]]() into the API, setglobal() and [[API getglobal|getglobal]]() are somewhat superfluous. You can always do something along the lines of:
  local _G = getfenv()
  local prevval = _G["MyVariable"]   ''-- "getglobal()"''
  _G["MyVariable"] = 1234            ''-- "setglobal()"''

Function calls always cost some overhead, so if a large number of getglobal calls are being made, the getfenv table will be a faster route.  Note that for few or infrequent calls the performance gain of this method is negligible.
