A little more info on this - after tracking the set character output
back through the code, it looks like i-output.boot.pamphlet is where
the font definitions take place.
Some of the definitions appear using this form:
SETANDFILEQ($plainSpecialCharacters0,[
EBCDIC( 78), -- upper left corner (+)
EBCDIC( 78), -- upper right corner (+)
etc.
EBCDIC would appear to refer to Extended Binary Coded Decimal
Interchange Code, apparently an alternative to ASCII.
http://en.wikipedia.org/wiki/EBCDIC
Judging by the chart on wikipedia, 78 would be 4E in hexadecimal which
is indeed the + character. plainRTspecialCharacters seems to hold
definitions not relying on the EBCDIC encoding. As near as I can tell
there are several styles of character output for EBCDIC plain and
default, and the RT definitions which appear to be the ones which work
on modern systems.
Interesting. I wonder how much flexibility is built into this
arrangement. Perhaps character sets which look better than either
default or plain could be selected.
Cheers,
CY
