I see it all the time: HTML sent via e-mail is quoted-printable
encoded.

Your file was 228K. No way you're gonna use XPL to process a 228K
file "all in memory". Force more than 4 or 5K of data (tops!) into
a Save/Get, and you're asking for trouble.

Moreover, QPEncode and QPDecode (the U2 routines) stress meticulous
observance of MIME standards over speed -- though, considering the
computation involved, the speed isn't bad, for XPL. (Wait 18 months
and the speed will double.) And they're optimized for encoding and
decoding XyWrite|NotaBene docs and XPL code: they understand
functions, wildcards, Speedos and other 3-byte characters --
critical on the decoding end. In some mail programs I've seen, the
quoted-printable implementation is so weak that XPL doesn't decode
accurately. QPD fills that breach.
