A few questions: 1. ORG - Assembler directive right? To make sure the actual code gets stored in the correct memory bank location? 2. CODE - Assembler directive? I guess my real question for ORG and CODE is what would happen if I didn't address the correct memory locations or left them out completely? Is there some documentation on this somewhere? 3. EQU - why use EQU instead of #define? Define and EQU are both assembler directives right? 4. res - Is this just reserving memory for a register? What are the units used here, a word? example: btcnt res 1 5. What is this? cblock 0x20 count endc Anyone know where I can find documentation on these assembler directives?
