There is a number to be added to the text in that column... That is a
slight edit though it still needs to be a number

I need to first find if the csound command is in the line and then go
to the n'th word (a number) and add another number to it. I may need
to do that for up to 5 values in the line (maybe more for cound
commands that haven't been thought up yet). I then convert the data
back to text. These all point to ftable's when I renumber them i.e.
f1 to f3 I have to renumber them in the program file as well. .orc
and .sco.
If I load in a 5 from the file it means I have to load the data from
the 5th column and add a number to it and save it back as text. I
have found that the .close is automatically called and sometimes you
can try to close a closed file causing an error.. So I let python do
it.. instead of coding this in awk I try to emulate grid code that I
have.. I will study this though and it does have code that is useful
and helpful.
this is the easy command list I will try to do lists with var number
of commands by counting the number of words in a line ,'s exc..
