Appendix C: Memory Allocation
Your very first program instruction will commit R
an uncommitted register to a program register. Your eighth program
instruction commits R
is encountered. Registers from the data storage pool (at power-up, this is R
and below) are not available for program memory without reallocating
registers using m %.
Two-Byte Program Instructions
The following instructions are the only ones which require two bytes of
calculator memory. (All others require only one byte.)
