Re: Stack preservation

Hey - nice use of DSE, I didn't know that if cc is zero it defaults to one. Very useful. I found ISG a cleaner way to increment the stack pointer, even though it always skips the next instruction. Less overhead than 1, ST+ and all that stack rigmarole.

Stack preservation

I dunno about you guys but I like my programs to be "function-like" and not leave junk on the stack, simple return the result in the X register. Here are some routines that accomplish saving and restoring of the stack and the lastX value, while returning whatever value is in the X register...

Re: DM41X arrived in Australia!

Most mail to Oz comes by air these days. By ship would have taken *must* longer. There are a lot fewer planes flying here than the USA. Pauli Tell me about it, I ordered Nightwish's "new" album from Finland back in February, it did not arrive until late September! Over 7 months!!! So I wa...

Re: Proposal for CST/CONF

I like the CST function and the A to P keys that allow you to quickly execute programs. However the stack is not visible. I tend to write most of my programs as functions, key in the value, run the program, return the result in the X register. Simple. Perhaps a CST mode could be added to show at lea...

Re: Multiple programs in a RAW file?

I wasn't REALLY a size problem. I have now successfully loaded the 23 programs in one raw file by separating them by RTN statements instead of END statements. Same size.

When I feel brave enough I will try and reproduce the error. I'm still getting everything setup the way I like it.

Re: Multiple programs in a RAW file?

Good idea! TRY AGAIN means it has run out of program memory or you've tried to run SIZE with too large a value. Which is odd because there was no program in memory at the time. Perhaps my attempt to load multiple programs separated by END statements in one raw file did something odd to the memory co...

Re: Multiple programs in a RAW file?

Okay - had to hit the RESET button on the back to clear that error.

All working now - yay!

Re: Multiple programs in a RAW file?

I cannot load any programs now! The TRY AGAIN error occurs every time.

Re: Multiple programs in a RAW file?

So ... replaced all my END statements with RTN statements. The DM42 programming tool automatically generated a final END for me. Now when I try to load the raw file the DM41X says "TRY AGAIN". I can't find any reference to this message in the user manual. So I guess I'll have to load them ...
