Hi there,

I have problem with writng "\4" into a file, for example, I want to
write a string "aaa\4024_folder\mm" into a file test.cfg. But once the
string wrote into file, it is "aaa024_folder\mm". So, i do this,

string="aaa\4024_folder\mm"
string=string.sub(/\\4/,"\\4") the result is the same.

I tried string=string.sub(/\\4/,"\\4"), the result is showed a square

Any one has any idea to solve the problem? Thank you in advance.
