How to input text on every 2nd line?
I have a file in two columns consisting of only numbers. I would like to put a string (the same textstring) on every second line, so that
501006 420.000
401602 165.000
.
.
.
becomes:
*Some_text
501006 420.000
*Some_text
401602 165.000
*Some_text
.
.
.
Are you up for it?
Thx...
