halo guys,
my newest problem is to read a specific value from a file.
the problem is, this are random values with different length and some are negative. thatswhy a simple jumping to a position wont help me. here a small example what i mean:

text file:

0.56 1234.45 0 -87.45 98.4 -54 and so on

now i want read just the fifth value automaticaly. how to jump directly to its position and read it? has anyone an idea how to solve it?

thanks in advance

A simple way is to use file_var_read and "waste" four calls to get the 5th variable.

thanks for reply,
the same solution i tried already, but my file has couple of thousands of this values. to read sequentially till value 16754 takes too long. thatswhy i want to speed it up somehow.

Maybe this could be useful in your case? Or is there no way to change the format of the saved values?

ok, since every dataset of mine contains 60 values i count now the bytes of each dataset and write them into a separate file. this way i can access the separate datasets directly by seeking in the data file using the byte information out of the additional file.

thanks a lot for help
