Using 'if bit set'

This program demonstrates calling one of two subroutines depending on whether the least significant bit of 'b10' is set or not. If set the value in 'b10' is odd, if not the value is even.

Code Example:

main:
	b10 = b10 + 1
	if b10 bit 0 set then
	  gosub oddvalue
	else
	  gosub evenvalue
	end if
	goto main
