What is the correct declaration/process (in C) for storing a value in memory and having it permanent so it can be updated or changed anywhere in code? Thanks, Dewayne

Hi Dewayne, > What is the correct declaration/process (in C) for storing a value in > memory and having it permanent so it can be updated or changed > anywhere in code? Read up on the definition of Global Variable. Decent C book that covers all skill levels: "C the complete reference" by Herbert Schildt ISBN 0-07-882101-0 It's the only one they had at Computer Literacy many years ago, so that's got to say something. What part of the country are you from Dewayne? Joel

Thanks Joel! I'm from LA. You? My question is more ARM specific. I figured it might be with the global but I'm wasn't sure if it reserves a specific part of memory or if there was something else. Thanks again, Dewayne
