HP-41 barcodes... via the web browser



#5

I'm working on a little program for generating program barcodes for the HP-41, in the form of a simple web page with Javascript code to parse the program and generate the bar codes.

It's beginning to look complete, but I'd like some example programs (as plain text) to test with. I would also like to know if there is a "canonical" mapping for certain HP-41 characters that are not available in USASCII (like ∑ (Sigma), ≠ (not-equal), etc)...

Any pointers to program listings or other information?


#6

Plain text listings in the program section here:

Thank you - that should help a lot!

#8

Very Nice :)

#9

Have you looked at the source code to http://www.hpmuseum.org/software/41uc.htm. That should help answer your question and also provide some help with your code. I used it to generate barcodes for web pages, e.g. http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv020.cgi?read=193137#193137 (message #26).

I couldn't find the source code there, but that may not be all that important - it seems that I have everything (yeah, right) working. I'll probably implement some of the "compiler rules" described for 41uc, as they seem to make sense - and are probably used in other places, too.

Thanks!

At the bottom of http://www.hpmuseum.org/software/41uc.htm is a link to Warren Furlow's web site. There you can get the source to HP41UC and the latest version.

Or, I can email it to you. Even if you do not need it, it may be a nice to have.
