 +===== Global =====
  
 +==== Format ====
 +**global** //variable list//\\
 +
 +==== Description ====
 +
 +Global will define a list of one or more (comma separated) variables that will be accessible and changeable within [[subroutine|Subroutine]]s and [[Function|Function]]s. ​ These variables can be simple variables, or array variables.
 +
 +Global variables can only be defined outside of any block statement and should be defined BEFORE you call a [[Function|Function]] or [[subroutine|Subroutine]].
 +
 +==== Example ====
 +
 +<​code>​
 +global a, name$
 +dim a(10)
 +dim name$(10)
 +a = {1,​4,​6,​8,​45,​34,​76,​98,​43,​12}
 +name$ = {"​Bob","​Sue","​Sam","​Jim","​Luis","​Guido","​Steve","​Angela","​Joe","​Paul"​} ​
 +t = 99
 +call printnames()
 +print t + " was unchanged - not global"​
 +end
 +
 +subroutine printnames()
 +  for t = 0 to name$[?] -1
 +    print a[t] + " " + name$[t]
 +  next t
 +end subroutine
