Global

Global (Statement)

Format

global global_variable_list\

Description

Global will define a list of one or more (comma separated) variables that will be accessible and changeable within Subroutines and Functions. 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 or Subroutine.

Example

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
