Re: GNU Awk 3.1.5 proglems with OFS

[Aharon Robbins]

Greetings.

Gawk is behaving just fine. OFS only comes into play when using the
print command with commas to separate values, or if you rebuild the
record.  However, $0 is the entire _original_ input record, including
the whitespace.

$ gawk 'BEGIN { OFS = "|" ; print 1, 2, 3 }'
1|2|3
$ echo a b c | gawk 'BEGIN { OFS = "|" } ; { print $1, $2 ; print $0 }'         
      
a|b
a b c
$ echo a b c | gawk 'BEGIN { OFS = "|" } ; { $1 = $1 ; print $0 }'
a|b|c

Hope this helps,

Arnold
