OTHER TOOLS AND RESOURCES:
A) 256 Library of the HP49G/49G+/50G:
To study the internal encoding of Graphic Objects we will use the commands:
-->H: given an object on the stack, returns a string of characters with its encoding.
H-->: does the reverse process to the previous command.
B) Jazz50G
The Jazz50 Debugger.
See the contents of the Saturn registers while we execute our code step by step.
Use the disassembler to see what our code would look like written in Jazz notation.
