Tom - upon re-reading the vt220 font file does not refer to compression and
expansion, but to slash} and slash bar etc. anyway previous info should have
defined this for you. Yes there may be aproblem with the coco underlined chars.
These chars are not needed by IAPL but they are nice to have for completeness.
The vt220 unfortunately does not have 128 downloadable chars, only 94.
therefore I had to map the apl char as in #AV to a vt220 version, so the hex
value of say a quad internal to the pgm is not the same as the one sent to the
vt220. That should not present a problem for cocos if your font just uses the
vt220 char not the internal one. The problem comes in the underlined chars.
since I didn't ha}ive room for 128 apl chars in a 94 char downloadable font, i
omitted the undelined ones. when IAPL/os9 wishes to output an underlined char
it outputs a "set underline mode" cmd string, then the normal char, then the
"set normal mode" cmd string. This is not compatible with a coco i expect. The
best thing would be for you to upload to me a defn of the font you have created
similar to table 4.1 but giving the hex value you use, then I can incorporate
the font into the pgm itself. (PS do you have the #AV vector map in your
textbook?) If not I will upload to you by mail. Then we can do it right {_for
the coco.
