48g TEACH command and "Examples" directory
Hi everyone,
does anyone know where you can find the contents of the "Examples" directory that is generated in 48g with the TEACH command? I searched online and on HPmuseum without success. Or how can I extract it from the Droid48 simulator on my smartphone? Thank you in advance. Hardware: Hp48S - Hp50g (5x black + 1 blue) - HP39gII - Hp27s - Casio fx-CG50 |

One thing to be aware of: there will still be special characters in the code that are specific to the 48 (→ Σ √ π, among others). Using a program such as INOUT can be useful to substitute trigraphs for those special characters if moving the code between systems. |

Thank you for the reply. Unfortunately the problem is actually extracting any content from Droid48. As far as I know, it is only possible to push an object onto the stack but not vice versa.

If you have EMU48 you can use it with the 48G ROM to extract the directory. There is also this from hpcalc.org which may be of use.

RE: 48g TEACH command and "Examples" directory
For reference, here is a copy of the 'EXAMPLES' DIR object created by the TEACH command as a simple text file. It is a bit easier to read in a good text editor like Notepad++.
Edit: Added white space to original text file for readability. New file name:HP-48G TEACH DIR Contents - Rev 1.txt |

(this was the ultimate goal) EDIT: yes, it is possible and it works! Hardware: Hp48S - Hp50g (5x black + 1 blue) - HP39gII - Hp27s - Casio fx-CG50 |

Meyers) to be very useful to help export HP-48SX utility programs I have written over the decades into the HP-48 emulators I use on my smartphones. Thanks DavidM for pointing to that post. |

Indeed, the right-arrow characters in your text file come out as strange Unicode characters on my computer (Chrome on Debian Linux). Perhaps you could use INOUT on the file to create the proper trigraphs (e.g. \-> ). |

I should have thought of that. Here is a file with the contents of the HP-48G TEACH directory using the INOUT Program mentioned above. |

RE: 48g TEACH command and "Examples" directory
INOUT is convenient, but taking text with HP fonts and copying it in PRG mode is also not dramatic.
But to use INOUT I had to write it by hand starting from scratch because the link version would have to be converted using INOUT itself... it's an unsolvable loop! Hardware: Hp48S - Hp50g (5x black + 1 blue) - HP39gII - Hp27s - Casio fx-CG50 |

It didn't take too long as there were not that many of them. I also had to delete the string delimiters.
