It has to do with changing the HEX value of the character before the line you want to see in a different color. Using your file utility (DBU of PFE) bring up your source file / member and change to HEX mode (where you can change the actual hex values). Change the hex number. I think 22 is green, 23 is white. You will need to experiment. But anyway, once you get what you want your best bet is to make a COMMENTS source member with sample lines in the various colors. Then when you want to make different color comments, pull lines from this member and change the text.
