creating text files

[Derek]

This seems like a dumb question but I am a bit new new to Revolution, I am
much more used to php , and c style programming. I am trying to create a
text file with a name based on a variable  but this doesn't seem to be
straight froward. Open file requires a string  and doesn't seem to accept a
variable in place of the string , and set filename only seems to work for
images and players?? is there some escape symbols i can use or a way to
rename a text file ?

Thanks
