HP-71B Dynamic array allocation

[rprosperi]

Despite the apparent conflict between what the manual says and your observed results, I am confident the Emu71/Win is behaving exactly the same as a real 71B when it comes to how statements behave. Emu71 is emulating the 71b h/w and runs the original ROMs, it's not a simulator with some functions implemented possibly in a different or enhanced way. So it's likely you are simply expanding the matrices in a way that does not 'remove' any elements, i.e. never decreasing any matrix dimension.

As for your 71B, I can't say for sure, but I can narrow it down to one of your eBay buyers.

You're welcome!
