+ | ===== 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. | ||
+ | |||
+ | 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 ==== | ||
+ | |||
+ | < | ||
+ | global a, name$ | ||
+ | dim a(10) | ||
+ | dim name$(10) | ||
+ | a = {1, | ||
+ | name$ = {" | ||
+ | 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 | ||
