Hi Taha,

Apart from that you should not use the word 'matching' for string
comparison, you understood correctly. I tried your code and it worked
as you expected on the same version of Gawk:

GNU Awk 3.1.8
uname -as: 
Linux   2.6.34-ARCH #1 SMP PREEMPT Mon Jul 5 21:03:38 UTC 2010
i686   GNU/Linux

I can not think of any cause for the error you encountered, but
you might check:

  1) Whether your input lines do not start and end were you think 
     they do. This can happen with files from M$ and Mac. Gawk
     on Linux will expect \n line-ends, and no \r. 
  2) Whether the encoding of the input file is different from that of
     the code. I have had some problems with that in the past,
     although that was with real pattern matching, not string
     comparison.
  3) What localization is being inherited from you shell.


 Regards,
