I have always thought that it could work like this: - You have a file you are reading in keyed order, and if you perform a READE - The system reads a block of records, in keyed order into the buffer. - If you issue another READE with the same key, the buffer is searched FIRST for a matching key, before going out to disk again But instead, we are forced to code the key-change detection ourselves, and use READ. Thankfully, it isn't difficult. -- "Enter any 11-digit prime number to continue..."
