Re: Copy, Translate, and Save Text File

Thank you for your help Ike, and the others who have helped me make progres=
s on this.

The attached code (without the indented code in the middle - see below) wor=
ks to read a user-entered text file and then output values from the map to =
a new text file. However, I need to make a copy of the user input file firs=
t, because I want to modify its contents, and I don't want to risk damaging=
 the original file. (I want to remove the first five characters from each l=
ine of nine characters in the input file before testing them against the ma=
p. I also have to deal with a header in the input file, but that is too muc=
h for me right now.)

When I added the code to copy the file (indented in middle of code attached=
 below), it copied the file to a new file as intended, but then the map rou=
tine, which worked fine without the new code, returned the error "Sorry '' =
Not in move list." How can I fix the code so that both parts work to (1) co=
py the input file to a new file, and (2) return the map values to the outpu=
t file?

Thanks for your help.
