IF STATMENT

[kamsabeti]

How can I use the IF statment for the this code:

npt = substr($0,24,12)

IF npt <> "" THEN DO THIS ELSE npt = "0"
{ # Insert "-" after each group of 5 chars.
gsub( /...../, "&-", npt )
# Remove any trailing "-".
sub( /- *$/, "", npt )
}

 if (npt != "") {
  # Insert "-" after each group of 5 chars.
  gsub( /...../, "&-", npt )
  # Remove any trailing "-".
  sub( /- *$/, "", npt )
} else {
  npt = 0
}
