HP 41: new barcode creation tool
Message #1 Posted by MichaelG on 8 July 2013, 12:46 p.m.

As you might remember I released a first version of my FOCAL Compiler/decompiler more than one year ago. The package now got a major enhancement: the compiler now can create Barcodes.
I decided to create one JPG file per page. The dimensions of the JPG are big enough to fit at 300 dpi on a DIN A4 or letter paper (minus some border).
You'll find the download package here:
download.michael-goericke.de/hp41/FocalComp.zip
The compiler is written in C# and requires an installation of the .Net Framework 4.5.

Thank you sooooooooooooooooo much. I have been trying to use Leo Duran's program to compiled HP-41C text files into .raw, with no success using Windows 7. You utility works well. I tried a very simple program and got its .raw file with no problem!!

Michael,
I browsed through you manual and I must say that I like very much the directives, the ability to include comments, and the support for a rich set of commands including extended functions and XROMs. Very nice work!!!

FocalComp Bugs??
Message #7 Posted by Namir on 9 July 2013, 3:22 a.m.,
in response to message #1 by MichaelG

Hi Michael,
I compiled the following program:
LBL "ZETA" CHS STO 01 1 STO 00 ENTER LBL 01 CLX SIGN RCL 00 + STO 00 RCL 01 Y^X - CHS LASTX RND X#0? GTO 01 SIGN 2 RCL 01 Y^X ST+ X - / ABS END
The compiler replaced the CHS with a subtraction operation. Also, the GTO 01 translated into a GTO 00. Can you please check if it is not a bug?
In compiling another program, the compiler rejected all occurrences of the X<>Y command.
Thanks!
Namir

I confirm this behaviour, further you cannot use tabs in source listing (e.g. before a comment).

Unexpected FocalComp Bonus Feature????
Message #14 Posted by Namir on 9 July 2013, 10:29 a.m.,
in response to message #1 by MichaelG

I don't know if the FocalComp documentation mentions it, but the FocalComp compiler DOES support code that accesses the M, N, O, and P synthetic registers. This is a much welcome feature since some of the HP-41C code written by Jean-Marc Baillard uses these synthetic registers.

I see the demand. Right now I don't use Special Features from .Net 4.5. .Net 4.0 is the last version supported on XP. I built 2 Versions, one for 4.0 and one for 3.0:
download.michael-goericke.de/hp41/FocalCompNet4.zip
download.michael-goericke.de/hp41/FocalCompNet3.zip
For the time being I can stay at .Net 4.0. The .Net 3.0 Version is for test purposes only.

Hello Michael,
many thanks for the 3.0 and 4.0 versions:-)
I tested the 3.0 on a machine running XP, and it works fine so far, including barcode generation!
Printing without modifying printer settings leads to very small barcodes. I wasn't aware that the Wand can scan those small but high resolution barcodes, but it works....

You Keep me busy :-) Thx again for your finding. x=0? works now.
The floating point values issue is a matter of documention (which I added now). Floating point values may not contain blanks. The exponent starts with an "e". A valid value is -12345.67e-89.
Please find the new version here:

This package contains both versions for .Net 4.0 and 3.0.

Could it be that your program uses single character lables in the range 112-122? The expected range is "A" to "J" and "a" to "e". The mentioned gap in between is not checked right now and the decompiler would Crash (already added "T" to "Q" and "R").

I created a very special version for you. That version catches the exception and dumps the last statement that caused the exception. The Output Looks like this: Exception caught on statement: 145 110
and helps me to identify the problem.

Hi Michael, I sent two raw files to your email that cause issues. I ran the debugging version you provide and it reports the offending statements; hope it helps diagnose things.
Many thanks for troubleshooting this wrinkle, hope you find the solution - your tools are tremendous for documentation, storage and archival.

Hi again, I looked at the partial outputs the debugging version produces to see where it aborted. In one case (for TYLR10.RAW) it was a "GTO E" instruction, and in the other case (PFE.RAW) it was 'RCL 04'.
I also noticed that one 'RCL O' in the first case was wrongly reported as 'XEQ O'

Wunderful. What different spacing do you mean?
But I found a severe issue (Compiler and decompiler) with the GTO statement :-( While Ángel's findings were easy to fix (thx for sending the data) I need some more tests to verify the fix for the GTO. My plan is to release the next version today or tomorrow.

The next version is available. Changes:

- added page #, date/time and filename to the Header of each page
- the barcode is a bit wider and uses the full width of the page
- the decompiler creates "ENTER^" instead of "ENTER" while the compiler accepts both versions

Michael the decompiler works like a charm now, thanks for fixing the problems. I still have one glitch: the compiler doesn't recognize the synthetic statements using exponents without the leading one, i.e. "E3", or "E-7". Can you also add support for those, they're widely used. (including the single "E" as a replacement for "1")
Also I get exception errors trying to produce the barcode for TYLR10.TXT (one of the files I sent you). It could be related to this as well, or maybe I should use the .NET3 for barcode generation on a XP machine?
Sorry I'm still reporting wrinkles, it's looking better and better each time.

I didn't change anything in font handling. The dump points to the code that creates the new page Header (which in fact is a copy of the other print text line).
