Hello. What you see is in the definition of the JC instruction. See the attached PDF for the in-software HELP description. The focus sentence is..
It makes perfect sense that the line following the JUMP should have the RLO in a TRUE state. BR Attachmenthelp-jc.pdf (218 Downloads) |

Hi dany brown it's perfectly correct what you see as the JC will set the RLO to 1 (press F1 on it and the help will tell you the same). You can think of the humble JC statement as a single STL instruction that is akin to an IF THEN ELSE high level langue construct. IF RLO is 1 THEN jump to label to continue there, ELSE set RLO to 1 and use as you see fit Your example logic is shooting itself in the foot as the JC jump destination is the next line behind the JC statement itself so instead of being an IF THEN ELSE it is more like a "always do it no matter what" |
