Keystroke recording on 50G (quite long...)
Message #1 Posted by Giancarlo (Italy) on 27 Feb 2007, 9:53 a.m.

Hi all.
As often happens to me, reading one of the most recent Forum post (guess which one...)
reminded me to share a little exprience of mine with you.
Even if this Forum is devoted mainly to vintage HP calc, my story is about the 50G - sorry :)
Frankly speaking, it has already been posted on comp.sys.hp48, but I hoped it might be
interesting here as well....

FOREWORD As a contributor to the HP calculators forum (, I thought it would be fine to get (“automatically” and straight away from the emulator) the list of keystrokes on the 50G when trying to reproduce an issue or suggesting a solution….

So, I needed a keystroke recording program for the 50G and found this one on

The program, unfortunately, does not "run in the background" (as macro recording on Excel does...) - I mean: it records the keystrokes but in the meanwhile does not let the calc do what the keystrokes are intended to.

Ideally, I liked to:

1. start the keylogging program - running in background 2. do whatever I like on the calc 3. stop the keylogging progam 4. get a log file with the keystrokes

Then, on comp.sys.hp48, John Gustaf Stebbins pointed me to his own program on

but, in the meanwhile, as I had not been able to retrieve Stebbins' software by myself, I had gone the "dumb" way, by doing the following:

>>> on the 50G emulator bundled into Debug4x package (by William G. Graves -, I used the

Tools--->Macro---> Record


>>> this left me with a .MAC file, which I was able to convert to plain text by using the Mac2txt.exe utility which comes with the above emulator; >>> afterwards, on Cristoph Giesselink's homepage, I downloaded the latest version of KML (Keyboard Mapping Language) documentation:

where I could find the "OutIn codes” for the HP49G keyboard. They were helpful to understand how to translate entries on the text files like

"P 3 1"


"press [0]"

>>> I arranged an Excel file with one column filled by all the OutIn codes, and aside each single substitution to be made, written in a "comprehensible and descriptive" language (like the "press [0]" above); >>> I got a shareware (RQ Search and Replace v. 1.72-2 by Andrew Shelkovenko) to make multiple search-and-replace operations on a file (I couldn't imagine it was so difficult to find a suitable one - or I was not so smart in the quest :/ ) - I needed one that could "learn" the search-and-replace pairs from a file (the .xls file I had already set up) >>> eventually, the steps I could perform were:

1. record a macro on the 50G emulator 2. convert the .mac file to a .txt file 3. feed the RQ Search and Replace program with the .txt file 4. get a file with all the keypresses translated into "descriptive" language.

I just liked to share this with the Forum – maybe some of you were not too bored by my story :-) And maybe somebody could point me to a "friendlier" program to perform multiple search-and-replace, or to a brand new and more efficient method to achieve my goal...

Any feedback will be appreciated. Best regards. Giancarlo
