No it works fine now.  I had another script running that created a global variable for path and file but then I stored that file name in a local variable.  This caused the issue.  When I use the global variable, it works fine!

Working now.  I just simplified the variables and it is working.  I had been saving the file name from a variable into an easier variable. Leaving it in the first variable worked.

Could be an issue since i first open the file to read it then check to find a zero length.  Then close it and reopen it for writing

That is whatI am doing but the strange thing is it works only when there is at least one character on rhe first line.

I have tried all kinds of manipulations.  Everything works as expected with a file that is not empty.

Nothing works on an empty file...

I cannot get Lua to write to an empty file.  I create the file nicely and if I put a character on the first line then the write command works fine
If I create a file which is empty, then the commands do not work.

Anyone have this problem?

THanks

Reply from Polabs this is correct.  Register is fraction of total value. So 1=3.3 volts
