Novice: using string manipulation in FEMM / LUA

[André Pubanz <pubanz@...>]

Hi all,

I use the Finite Element Program FEMM which has a LUA (V4.0) 
implementation to do modelling of magnetic systems. Up till now it works 
fine, I can use LUA scripts to manipulate program flow and automatically 
built models.

But now I would like to use string manipulation. In the Manual (LUA 
5.0!!) it states that the string manipulation library must be used. I 
haven't got a clue on how to do this (I searched the archives and 
FAQ's). Obviously FEMM was built together with the LUA pieces as I can;t 
find any specific LUA stuff in the install directory.
I want to be a user of FEMM only, without having to get deeply involved 
in LUA itself.
Is there a simple way to do this?

Regards,

Andre
