To break the file up and adding a directory is what a database is about. . .Here its just the file as it is. . .The use of SetStreamPosition is the very time consuming issue. . .See some timing figures in update above.

OK. . .I am quit lucky whit this. . .The last fraction digit is not as expected. It is 57 here but should be a 567.

You want to produce a couple of numbers. Like the one shown. . .You like to build this numbers from parameters as shown. . .So you get this kind of long numbers as shown.

Have an other look. It seems not to get the last words. . .If you do {m, n}={1, 4}

OK. . .Your function works well. . .It could not improve in timing compared to the algorithmic one shown below.

Shure. . . .Your are right. . .The variable named wb is of course the wordlenght of the original code above. Please modify it accordingly. . .The comparison reached the following results:. . .yours 4.9 sec. . . the other 1.3 sec

OK. . .A fast algorithmic solution was found. . .(see Update). . .Timing for 4.000.000 records. . .This function 23 sec, the algorithmic solution 1.3 sec
