hi, i have written a little code that will fire our pistons for approx. 3 seconds when one of the joystick buttons is pushed, so I wrote an if statement after the SERIN that

"if p2_sw_trig = 1 then GOSUB FIRE3"

that works and sends it to my sub code which looks like this:


FIRE3:
relay1_fwd = 1
MyCounter VAR byte
StepSize VAR byte

MyCounter = 1

FOR MyCounter = 1 TO 3001 STEP StepSize
StepSize = delta_t * 25
NEXT

relay1_fwd = 0
RETURN


but once i push the trigger, i get a basic run error, but, when i take away the FOR...NEXT statements, everything works, what's up with this? can i not do loops inside of subs? thanks a lot

Stephen
MyCounter is declared as a byte. A byte can store a number no larger than 254. After that it loops around to a negative number (an illusion).
