8 Level Stack?

[TomC]

How do I set the stack height to 8?

I do recall doing this - perhaps on an early version.

Did it 'go away'? At what software level?

Thanks,

Perhaps you were using a WP-34S? I don't think Free42 or DM42 has ever had an 8 level stack (and neither has the HP-42S).

... but it will come back with the 43S. Please see "Discuss".

I can confirm that the DM42 has never had an 8-level stack!

This would be an excellent feature for a potential Free42+ fork. Expand the flags to 3-digits for toggling advanced features, then add an 8-level stack, secondary alpha register that can be swapped in and out by toggling a flag, PUSH/POP instructions to save/restore the whole stack, alpha, and flags, etc.

Hmmh, let's see:

What for do you need more than 100 flags? Please specify.

Done for the 43S (and present on the WP34S and WP31S already).

We'll give you an infinite number of alpha registers on the 43S.

alpha, and flags, etc.

More alpha? More flags? Please elaborate.

Thank you all - sorry for the confusion/extra efforts.

Perhaps in my excitement with the DM42, my synapses crossed!

Cheers,

In the context of Free42, they would just be used for adding additional toggles for for enabling/disabling enhancements that could break compatibility with the original 42S. For example, "SF 101" might enable an 8-level stack. The 00-99 flag space is already pretty much spoken for, so adding 100-199 would be necessary.

Well there go all those programs I wrote that depend on there only being 100 flags total!

Don't you panic! Nothing's decided about 8 levels yet but they will be implemented in 43S for sure. And in 43S, 100 global flags will be provided plus optional 16 local flags per program so far.
