Hi Wade (and others),
Thanks for all the suggestions. I had also stumbled on the code in
cgiReadParse() and ended up adapting that code for my purpose.
cgiReadParse() was too specific for my needs - besides looking
directly at $QUERY_STRING, it also only decodes values and the
case I'm looking at needs to decode names as well. (Oddly
enough, you seem to be able to use arbitrary strings for names
of input fields in HTML forms...)
For the record, here's what I used - others of you had nice
solutions as well!
------------------------------------------------
procedure cgiUnmapHtmlEscapes(s)
static hexen
initial hex := cset(&digits || "ABCDEF")
while s ?:= tab(upto('%')) ||
(="%",
(c1 := tab(any(hex))) & (c2 := tab(any(hex))),
cgiHexchar(c1,c2)) ||
tab(0)
return s
end
-----------------------------------------------
Thanks again!
