I hate to see novices do this instead of: 4 + 16 * ( 3 + 16 * ( 2 + 16 * ( 1 + 16 * 11 ) ) ) I once spotted this when I investigated why EXP and LN were appearing in a link edit map. ... but I suppose if your optimizing compiler does operator strength reduction well, it doesn't matter. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
