That was very elegant! It actually gives a count for each state. I will try to parse the syntax so I can build such awk commands myself. Thanks.

textutil::repeat(n)				    Text and string utilities, macro processing 			       textutil::repeat(n)

__________________________________________________________________________________________________________________________________________________

NAME

       textutil::repeat - Procedures to repeat strings.

SYNOPSIS

       package require Tcl  8.2

       package require textutil::repeat  ?0.7?

       ::textutil::repeat::strRepeat text num

       ::textutil::repeat::blank num

_________________________________________________________________

DESCRIPTION

       The package textutil::repeat provides commands to generate long strings by repeating a shorter string many times.

       The complete set of procedures is described below.

       ::textutil::repeat::strRepeat text num
	      This  command returns a string containing the text repeated num times. The repetitions are joined without characters between them. A
	      value of num <= 0 causes the command to return an empty string.

	      Note: If the Tcl core the package is loaded in provides the command string repeat then this  command  will  be  implemented  in  its
	      terms, for maximum possible speed. Otherwise a fast implementation in Tcl will be used.

       ::textutil::repeat::blank num
	      A convenience command. Returns a string of num spaces.

BUGS, IDEAS, FEEDBACK
       This document, and the package it describes, will undoubtedly contain bugs and other problems.  Please report such in the category textutil
       of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883].  Please also report any ideas for enhancements you may have for
       either package and/or documentation.
