dear bruce,

i failed to initialized the WORD but in my program. also my bad, this is my code.

Code:
        init:
		decideInterval		var		WORD
		TIMEINTERVAL		con		600
                decideInterval = 0

	main:
                decideInterval = decideInterval + 1
		IF decideInterval = TIMEINTERVAL then
			decideInterval = 0                           ;resets the decideInteval
			(a command output to LCD display)
                ELSE
		ENDIF
		GOTO	MAIN
	
		END
i verified it that it enters the IF/THEN statement with the decideInterval = 11 or other pseudo-randomly values. sorry for the incomplete info a while ago. but this post seems to be complete now.

thanks

regards,
yettie
