Write good code and forget about instruction timings. With any luck your code will have to perform on several generations of architecture and machines.
There's a big difference between B- (base-index-displacement) branches and J- (or BR-) (relative address) instructions. Surely by now, this should go without saying. Regardless of whether they're "faster" or not, they are much better, and as that is well-documented, I won't belabor it. sas ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
