===== Global (Statement) =====

==== Format ====
**global** [[variables|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
</code>
displays\\
<code>
1 Bob
4 Sue
6 Sam
8 Jim
45 Luis
34 Guido
76 Steve
