Hello

FlyingSquirrel's answer works great.

I thought 3 points might be useful:

1)
Going back to your orig attempt, your line 7:

count = $(expr $count +1)

would work if you used 'backticks' like this:

count = `expr $count + 1`

2)
Also - I am not sure why you have a double dereference in line 6:

echo ${$count}

You do not need the extra 'dollar sign'

3)

Maybe more of a stylistic issue... For the builtin variables (ie the positional variable $#) I like to throw that into my own variable - as it makes the script more legible and I dont have to worry about unintended changes.

time

time(1T)						       Tcl Built-In Commands							  time(1T)

__________________________________________________________________________________________________________________________________________________

NAME

       time - Time the execution of a script

SYNOPSIS

       time script ?count?
_________________________________________________________________

DESCRIPTION

       This command will call the Tcl interpreter count times to evaluate script (or once if count isn't specified).  It will then return a string
       of the form
	      503 microseconds per iteration
       which indicates the average amount of time required per iteration, in microseconds.  Time is measured in elapsed time, not CPU time.

EXAMPLE

       Estimate how long it takes for a simple Tcl for loop to count to a thousand:
	      time {
		  for {set i 0} {$i<1000} {incr i} {
		      # empty body
		  }
	      }

SEE ALSO
