I looked over the forum & does any one have a nice small sub-routine to create true lower case in XB I can insert into my program?

Also, we need a space where we can post little helpful subroutines like this that people have come up with and can be inserted into other programs. I guess this topic is a good place as any. that is, if someone hasn't already created such a topic. No reason to re-invent the wheel if someone else has already created it and fitted it with mags.

Are you looking for an XB coded subroutine or an ALC routine that is LOADed and LINKed from XB?

If you like the lower case characters that are in the 99/8’s character set, it would be trivial to provide the character definitions.  Let me know if those work and I can get them from MAME and put it here.

Here is the font from ASCII 32 – 127 from my fbForth font file (FBFONT):

The reason I posted the entire font is that the blank row of pixels in this font is on the bottom to allow for true descenders, which would really look strange with only the new lowercase characters.

Hmm everything you can think of is in this Traveler 7Zip file.

The following code will work in both TI Basic (with E/A cartridge) and TI Extended Basic: 

100 CALL INIT
110 CALL LOAD("DSK1.FBFNTB.obj")
120 CALL LINK("FBFNTB")
130 PRINT " !""#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~"&CHR$(127)
140 GOTO 140

The following ZIP file has the source, object and listing files: FBFNTB.zip
