read specific line on text file

sendoh · 2008-07-04

Hi Guys,

when we use the read function of a file it will read the entire data inside the file, what If I only want to get a few data from the text (not the whole text), how can I do it?is there a way to do this in nav?
example data in textfile

1,eric,mexico,dev,,500,,,
2,roy,china,PM,,,,,
3,han,australia,dev,,400,,,
4..
5...
i want to start to read on line number 3 to the last.

Regards,

Sendoh

with

YourImportFileVariable.seek(Position)

you can set a file pointer to a new position in an ASCII or binary file

It depends. If you open the file in Text Mode, the read function will read whole line. If there is no end of line, it will read whole file. If you open the file in binary mode (TextMode := false), READ will read exactly same count of bytes how long is the target variable (e.g. if you are reading Text[30], it will read 30 characters etc.).
