Re: SOLVED Re: Prefix bug in ax_lua?

Hi Nate,

Glad you got things working. Sounds like you did a pretty thorough
analysis! The macro actually uses a little Lua script to deal with the
prefix, and that seemed like a likely place things could be going wrong. A
good guess, I guess. Anyway, I didn't realize you work on Hamlib. Never
used it myself, but it seems pretty neat.

Glad I could help!
