RE: (HP71B) ASM question

If there is a difference in HP71B? (dont know for now. I have to test this). Could not read any R0 or R1 impact in IDS Vol3. However, I will have a deeper look into this the next hours. How to use the debugger in EMU71? (no glue how to use a debugger). A short WebEx with anybody could be great. With the X*2 word, I had already a problem with MP2-15 when I had X multiply 2, which gave the wrong result. Its why I changed it to X + X. When we see the Forth/ASM IMS for the words X^2 (no stack change like RCL* but with 2 same parameters A-B * C-D which in fact A-B * A-B) or F* (Stack drop) , it uses MP2-15. I am still looking there what is the difference to the code of the RCL* word (no stack drop, A#C and B#D). Update: I will have a look to the path DV2-15 of 1/X15.. = multiply. Will see if its better on EMU71. HP71B 4TH/ASM/Multimod, HP41CV/X/Y & Nov64d, PILBOX, HP-IL 821.62A & 64A & 66A, Deb11 64b-PC & PI2 3 4 w/ ILPER, VIDEO80, V41 & EMU71, DM41X |
