access values from file

[tougo]

i have a *.txt with some values that some equations of my program must access so as to return results
how can i access the file and specify at which line of the *.txt is the correct value?
any help would be more than welcome

for example
i have in the txt 4 values

34.567
65.467
84.367
84.564

and i want to multiply the first with the last and i want the result in a Tlabel in my programme how can i access this values?

With the functions seek or fseek you can position the reading pointer to any place in the file.

A couple of options are to use a file stream object (see TFileStream) or perhaps an INI file style method (see TIniFile).
