Brad, Thanks for the quick reply... Well, rcs looks like a source control system, which _would_ allow me to create revision history files, but I was hoping that a file carried its version number in a file header, like the superblock structure, for quick access without having to create more files. This is a flash memory system, so storage constraints and access performance reign supreme. Not to mention that I'd have to include rcs as part of the distribution, taking up more memory in the flash file system. Keith -> -----Original Message----- -> From: Bradley D.
