unnecessary confusion w/ Convert cmd

[Angus]

Thank you for your explanation, parisse.
But isn't the symbol _in? Is the loop you mentioned usable code from within programs? So you can use the loop in a cas program but NOT in a home program? I didn't know such syntax is available at all.

Can you say that in cas mode there are other reserved words than in home? In cas mode is it your original core-code that parses the entry - there is no hp parser that would realize tokens like units? And is that the reason that there are numerous typos with the commands? You use a different spelling in xcas than hp used in their hp39 code? (I prefer to call it cas mode. I understand that often things come from xcas but when I switch my calculator into cas it is still the prime I hold in my hands. If mangling the xcas into the hp system causes so much trouble I would personally not have chosen that road in the design stage)

If there is no way around such things (I don't want to criticise again or question the design again) wouldn't it be better to get rid of _in and use _inch system wide? Although I hate unnecessary keystrokes and long symbols on a calculator keyboard ;-)
