data extraction using lua

["sthu111 <sthu111@xxxxxxxxx>" <sthu111@xxxxxxxxx>]

Maybe I am missing something, but I am trying to extract the 
magnitude of the flux density across a line. Normally I select PlotX-
Y and write file. I want to know how to do this using Lua 
scripting. Looking at the manual, I only see getpointvalue(x,y) 
which would mean I would have to create a recursive function to get a 
150 points between the two points I am looking at. My question is 
there a function not documented(or one that I missed) that would do 
the same function as stated before and put the data into a file using 
Lua scripting exactly like the why the PlotX-Y function does in the 
interactive window or do I have to do each point individually? Thank 
you for your help and thank you Mr. Meeker for your program.

P.S. Is there any plans to port to Linux/Unix?
