Re: Filename as Function Argument"

When writing strings to be used as filenames, use double \ as in
"c:\\my files\\blabla.txt"
Certain combination of the form \+character (such as \n) are interpreted as
"metacharacters" and the filename is not read properly. Since "\\" is the
metacharacter for \, the use of \\ solves the problem.
