Re: help request on HTTPAPI
Hello,
EXAMPLE18 demonstrates the currency converter. No need to modify EXAMPLE19.
I've noticed that a lot of the EXAMPLExx programs don't work. They
worked when they were first added to HTTPAPI, but the web servers have
changed over the years and discontinued the functionality. I'm going to
go over all of the EXAMPLE programs for the next release, and replace
the examples that don't work with different ones that do.
