As long as the "Variable=Value" URL form in Pico Lisp is limited to the
use of global variables, there are two problems:
1) How can you know how many (and which) variables that the request
contained?
2) Setting up the URL data to be used in the jQuery.getJSON call will be a
bit more work, as instead of writing data={*X=11, *Y=22} you have to do
this:
data={};
data["*X"]=11;
data["*Y"]=22;
For some reason I've had problems with string variables containing
letters. data["*Y"]="22" works, but data["*Y"]="2x2" don't. I'll try these
kind of data against another kind of server to see where the problem is.
