On slow computers when I issue FILETOSTR(), then some proccesing and then STRTOFILE() back, sometimes error file access denied occurs. I don't want to slow down program while proccesing because of few users :-(. So, I'm looking for a possible different solution.

May I ask what's wrong with using FileToStr()?

>Line lenght can be more than 254 bytes and before the time of proccesing I don't know lenght of a specific line.
