To return the status of the joystick triggers.
As a statement:
STRIG ON STRIG OFF
As a function:
x=STRIG(n)
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. |
