[BLKNUM] is the variable for outputting block numbers. But telling the post to Output Block Numbers, activates that variable. With no variable.... No output. With the variable, you have a choice to output or not.
Sometimes on a comment line you might not want block numbers, ever. But in the rest of the program you always want block numbers. You could remove the [BLKNUM] from the comment output section. That would keep it from ever outputting BlkNum's, no matter how the switch was set.
You might also want to put the post here as an attachment for others that might search this forum for "Edgecam Post 850SX Acramatics".
