Speed of HP-49G Routine for Tektronix Vector Graphics Terminal

[Martin Hepperle]

Werner,

so far I was not able to use you assembler variants.
I copied and pasted the assembler source so there should be no typing errors.
The earlier versions simply crashed my HP 49G and the last version returns a string with the wrong content.
The only thing I changed was that I prepended my scaling/translation transformation in front of the COERCE2.
Maybe I am doing something wrong i building the code object.
I simply use the classical HP-Tools chain rplcomp, sasm, sload to build the TEKXY.hp object.
With a command file under Windows this is no problem and the SysRPL code works as it should.
Then I load the result in Emu48 for testing and, if satisfied, I transfer the result to the calculator.

Of course, I would like to test the assembler version too. Maybe you can push me into the right track.
- On which platform/emulator did you test your code?
- Do you obtain the same results as in the examples below?

Sorry for all these questions,
Martin

Stack (top ... bottom, all must be Reals, which is ensured by the calling RPL program)
6: x0
5: y0
4: sx
3: sy
2: x
1: y
TEKXY
...result: dropped x, y replaced by 5 character string...
