I too would use the C39 extended set. I currently have to use an external
font package as well.

Dawn,
Do you have separate software fonts that allow these extended characters? I don't seem to be able to see it in the c39 that comes with R:Base 7.1, and got error messages, so I have to use the "Worth Data" fonts, instead of the native R;base set. A long, long time ago I put in an enhancement request (70973) to add extended character set, but since there is still no status assigned I assume it was pretty far down on the list, or just not available.

Yes. We have standard barcodes that are used in our ink making department that have the appropriate commands for saving the row, exiting the form or exiting the application. We just programmed our bar code readers to allow extended commands and used the manufacturers spec sheet to come up with the appropriate barcodes. For example: When we were using RBase for DOS, our "End Job" barcode, would escape to access the form menu and then execute a carriage return to choose Exit, then would answer the save changes question (always no in our case as the user was always on a blank line in a scrolling region). The barcode was %A$MN. %A is Escape, $M is Carriage Return and N is to say no to the save changes question. We had to change the barcode slightly when we went to 7.1 because the form was redesigned, but essentially, it does the same thing. We did this because other than exiting the form or application, there is no need for the user to otherwise use the keyboard - everything they need is barcoded; job numbers, part numbers, even the command to retrieve the weight from the scale. Having the commands barcoded means the only time they needed the keyboard or the mouse is when they were logging on or off.
Hope it helps.

Has anyone ever used the extended code 39? This allows for addfitional commands to be embedded in C39 like [ENTER], [F2], and [^], etc. I usually have to use the code convertors from Worth Data in California to get these. That way, you can embed all kinds of keystrokes into your barcode to add extra commands. This is useful if you are trying to emulate some other screen, like in a mainframe application, or any application that you have no control over.

Here's a pretty good site for understanding bar code symbology specs; Code
39 alpha characters all upper case.

Hope it helps.

Dennis,
I've used lowercase letters for barcodes using Code39 and never had that
issue. The font or software that I was using always converted it to
uppercase before creating the barcode I guess. Before Rbase provide
it's own barcodes I was using Carolina Barcode fonts, as well as using
embedded barcode fonts that came with our label printer software (Seiko
SmartLabel). If I entered 'vm1234' and showed the Human Readable under
the barcode, I would see "VM1234". My guess is Rbase does the same
thing.

RB7.1
Using the bar code option for labels, I used the RBase Code 39 to
replace the external one that we used previously.
Code 39 handles (coincidence?) 39 characters. Capital letters, numbers,
and a few special characters. If I have part number "VM1234", the bar
code prints fine using either the old or new bar code font. But, if it
is "vm1234" then the old font puts little boxes for the "vm" because it
is an invalid character and the RBase Code39 font puts barcodes. Not
sure what the barcodes are but just curious if this is an error.
TIA,
Dennis
