[bug-gawk] Is this a bug

[Seppo Lehtikangas]

Hi!

I have been using some time to find annoying error in my awk-code.

I had to strip almost the whole code to find the error because awk tells 
me that there is syntax-error on else-statement(line 12) while the fact 
is that error is on if-statement(line 9).

Is there some bug or do I have to learn other way interpreted error 
messages?

My code:
===============
#! /usr/bin/awk -f
# ~bin/iftest
#
{
#printf "%s %s %s %s \n", ARGV[0], ARGV[1], ARGV[2], ARGV[3]

#if (NF == 0) print "usage iftest [1 | anything]"

If ($1 == 1)
   {print "number one"
    printf "%s\n", $0}
else
   {if (NF == 0)
       {print "empty row"}
    else
       {print "non one"
       printf "%s\n", $0}}
}
===============
running code gives:
========
iftest test
awk: /mnt/L6EVM/seppo/bin/iftest.error:12: else
awk: /mnt/L6EVM/seppo/bin/iftest.error:12: ^ syntax error
========
