Specifications

If used inside the

SUB or FUNCTION function in the same file where the global variable is

defined, the variable will also have the same value.

(Example 2) The variable aa% defined by the

GLOBAL statement will have the same value as

aa% within the

FUNCTION.

File 1

File 2

GLOBAL aa% GLOBAL aa%

DECLARE SUB printaa(x) SUB printaa(x)

FUNCTION addaa(x) print aa%+x

addaa=aa%+x END SUB

END FUNCTION

aa%=2

print addaa(2)

printaa(2)

If you link Files 1 and 2 above into a program file, the variable aa% used in those files will have

the same value.

■

If a same name variable is used in one file where it is declared to be global

and in the other file where it is not declared

In those files where the variable is declared to be global by the GLOBAL statement, all of those

variables will have the same value. In a file where the variable is not declared, the variable is

available only in each file.

(Example) If in each of Files 1 and 2 the variable aa% is declared by the

GLOBAL statement

and in File 3 the variable aa% is not declared:

File 1

File 2 File 3

GLOBAL aa%[50] GLOBAL aa%[50] dim aa%[50]

If you link Files 1, 2, and 3 above into a program file, the variables aa% in Files 1 and 2 will

have the same value and aa% in File 3 will be treated as a variable different from those in Files

1 and 2.
