Hello: This should be easy but I cannot seem to get it working. I want to check if either flag is set to 1 but I consistently hit the else clause even though at least one flag is always 1. Any ideas will be appreciated. Thanks,Steve if ( isflagset(13) | isflagset(17) ) { ... } else { ... }; -- ISC Network Engineering The University of Pennsylvania 3401 Walnut Street, Suite 221A Philadelphia, PA 19104 voice: 215-573-8396 215-746-8001 fax: 215-898-9348 sip:blairs@upenn.edu
