Hi Thomas,
Alas, the only documentation for the methods themselves at this point is the inc and clw files. (netweb.inc and netweb.clw in your \clarion\libsrc folder).
In truth documenting each method is on the to-do list, but in isolation is not terribly useful. (At least it won't tell you hugely more than just reading the source). The really interesting doc is how the methods fit together, and how the code "flows" through your program, and that's also on the "to do" list.
Cheers
Bruce
