Bryce,
hello, I was looking at your new(ish) uuencode/decode on the Usenet
news, and I have 3 comments:
1/ It will fail disastrously (and often mysteriously) if run under MSDOS
unless you change the fopen access to "rb" in uuencode and "wb" in
uudecode.
2/ A further level of error-checking is possible. UUENCODE only uses 6 bits
of an 8-bit character. Assuming parity randomises the eighth bit, there
is still one left. This can be used to check for oddball character
translation problems, eg the tilde-caret change can be detected that
way. I feel it is wrong for UUDECODE just to mask out the six bits and
not look whether the seventh is zero. In fact one could implement parity
checking as well.
3/ "transparant" is not a word, even in the USA !
best wishes,
Andrew Wylie in sunny London.
