HP-41 Synth. Progr. Question
Message #1 Posted by Olaf on 31 Aug 2006, 7:29 a.m.

Hi again,

i just asked a question here about the byte grabber... and there is the next problem already. In the HP-41 Software Library on MoHPC is a program called morse code. In the program are 2 tones used, "TONE 8" and "TONE P". I didnt manage to get the "TONE P" yet. According to the byte code table i would take 0x50 which is a P. So i would key in "STO IND 31" to get the Tone followed by "LN" for the P. But what i get is a Tone 0. I read about that the Tone command maybe can not display the characters but the tone (sound) is definitely the wrong one.

So, can anybody give me a hint how to enter those "TONE P" ?

Thanks in advance,

Olaf

Hi,

To create TONE P you can type:

STO IND 31 X=Y?

then apply the byte grabber to the STO instruction. Note that the status register P 0x78 is different from the letter P 0x50

Thanks a lot!!!

That works :-)

I thought the P with the arrow was not the P shown in the Program listing...

Greetings,

Olaf
