sorry for my bad English.
i have a text with 132 fixed length lines.
i need to jump directly to the line number 457478.
but not with the a loop line by line... i know this way, i need to jump directly the line 457478.
Now after the code is in line number 457478, read, line-by-line, the rest of text to the end of text
The text file has approx 4500000 (4.5M) lines and the file size is approx 533 MB
