STRIG Statement and Function

Basic Computer Programming Language Command Set

Purpose::

To return the status of the joystick triggers.

Syntax:

As a statement: STRIG ON - STRIG OFF

As a function: x=STRIG(n)

Comments:

STRIG ON must be executed before any STRIG(n) function calls may be made. Once STRIG ON is executed, GW-BASIC will check to see if a button has been pressed before every statement is executed. STRIG OFF disables the checking.

x is a numeric variable for storing the result.

n is a numeric expression within the range of 0 to 7 that returns the following values:

Value of n - Returns

0 : -1 if trigger A1 was pressed since the last STRIG(0) statement; returns 0, if not.

1 : -1 if trigger A1 is currently pressed; returns 0, if not.

2 : -1 if trigger B1 was pressed since the last STRIG(2) statement; returns 0, if not.

3 : -1 if trigger B1 is currently pressed; returns 0, if not.

4 : -1 if trigger A2 was pressed since the last STRIG(4) statement; returns 0 if not.

5 : -1 if trigger A2 is currently pressed; returns 0, if not.
