Hello,

I would like to extract one or two fields of a line.

At the moment, I am extracting the first field of a line:
The line can have two or three fields delimited with a dot.

if three fields, I want to be able to get the first two
ie if line = X.Y.Z
output X.Y
if two fields, I want to be able to get the first one only.
ie if line = X.Y
output X

How can I do this ?

Thank you for any help
Max
