I want to change FS in awk, but not in BEGIN. I want to print word and the letter.
awk 'BEGIN{FS=""}{print $1; FS=" ";print $1; FS=""}'
Of course it does't work. Is there any function, way to show words's letters?

awk is record oriented. It won't allow resetting the FS while processing the same line. Judging from the code you've written, you would like to take, e.g., this input:
First
Second
and you would want to see as output:
F
First
S
Second
One way to do that with awk:
awk '{print substr($1,1,1) ; print $1}' inputfile
F
First
S
Second

1Could you give a sample input and desired output? What exactly are you trying to do? Would multiple field separators do the job? What should an empty FS do? – Fiximan – 2015-08-24T09:23:00.467
I found solution couple minutes ago. I use "split()" function. – diego9403 – 2015-08-24T17:52:29.913
