Thanks Ygor.

I have a file containing records e.g. file.dat below.

99.000 83.000 369.000...

Hehe!
First of all I want to give my appreciation for a quick answer.

Without knowing what the heck that code from Ygor meant I tested it in my script. It seemed to work partially in my case,...

55.000
113.000
33.000

25.000
9.000...
