Hi Group,

The following is a very simple program but I'm not
able to get the output.

$ awk -f summary.awk input.txt

where input.txt contains a single line

John Mary Anthony Suresh Sam

summary.awk contains:

print NR
print $0

The output gives NR as 1, FILENAME as input.txt,
BUT it is NOT printing anything for $0. I'm working on
SUN solaris machine.

$0 is only set within the line-oriented execution; It may be non-portable to assume that NR and FILENAME are.  Assuming what you want is the last line, try:

  print n
  print f
  print z
