QBasic 1.1 Commands List: CALL Statement

Syntax
[CALL] name [([argumentlist])]
Description / Parameter(s)
name The name of the SUB procedure to call.
argumentlist The variables or constants to pass to the SUB procedure. Separate multiple arguments with commas. Specify array arguments with the array name followed by empty parentheses.
If you omit the CALL keyword, also omit the parentheses around argumentlist. Either declare the procedure in a DECLARE statement before calling it, or save the program and QBasic automatically generates a DECLARE statement.
To specify an argument whose value will not be changed by the procedure, enclose the argument in parentheses.

Example

' The program REMLINE.BAS illustrates declaring FUNCTION and SUB ' procedures. To view or run this program, load REMLINE.BAS using the Open ' command from the File menu.
