Using RSemulate, according to technote 55723, i should be able to use the GCD instruction to test some logic but it seems as if its not working. i set it up as Source of I:0.0 and Dest of N7:0 and im getting nothing through to N7:0. Thought that whatever i put into the data file for the I:0.0 (111111111111111), i would get out into N7:0 as a binary number(4095). am i missing something?
