It's probably good enough to develop the algorithm. After you have the algorithm working, you can use PICCLITE to verify the converted syntax. It just won't link for you (you'll have to lie to it about what chip it's compiling for). Then you can submit the untested PICC code. I used to have CCS C. I got tired of Version du Jour and Bugs Fresco. By switching to HiTech I saved myself lots of time (money) and frustration (time).
