[WP 34s] Strange behaviour of [alpha]XEQ

[Bernd Grubert]

Hello.
I'm trying to use the [alpha]XEQ function, but it doesn't work as (I) expected. From the manual I understand, that this function XEQtes the function with the name corresponding to the alpha-data stored in the register that is given as parameter.
I tried the following code in in the emulator and in the real calculator (both version 3680):

Code:

**LBL'AXQ'
LBL A
CL[alpha]
[alpha]'F'
[alpha]STO 00
[alpha]XEQ 00
RTN
LBL B
LocR 001
CL[alpha]
[alpha]'F'
[alpha]STO .00
[alpha]XEQ .00
PopLR
END
**LBL'F'
END

I started both versions from RAM. The 'A' version works on my realbuild but not in the emulator. The 'B' version doen't work on both machines. The [alpha]XEQ produces "NO SUCH LABEL".

Am I missing something or is this a bug?

Regards
Bernd

Definitely something worth debugging.

I'd say bug here. They should behave the same.

My initial guess is we're not dealing properly with the length of the alpha data. But this is just a guess.

Found the bug and exterminated it.

Should work properly in the next build.

I've committed a new build to SF. Maybe before I assemble a new release package we should investigate the Y display optimizations. Is anybody willing to apply the patches? I can then do the building and packaging.

I've committed the patches to both the 34S and the 31S. If something needs to be fixed or debugged, let me know, I'm happy to help.

I've updated the builds again. Happy testing!
