Hi,
this is my first post. Sorry for the mistake, I am a French user.
I try to figure out to transmit an (FTP.put) with Mach4.
To test my lua program, I made a test with ZerobraneStudio without Mach4.
The transaction work fine with interpreters (lua, lua5.1, lua5.4) but not with 5.3

My Mach4 configuration is with 5.3 in the Mach4.lua file interpreter.

Is there any solution to make this work ?
What is the correction to make to Mach4 to use 5.4 libraries ?
