You have a read command at the start of your script and you have a read command inside your loop. Every read command will wait for you to type in a response.

Try replacing the first read with an echo or printf that gives the directions for the data to be entered and let the read command inside the loop be the only command that blocks waiting for data to be entered.

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

__________________________________________________________________________________________________________________________________________________

NAME
continue - Skip to the next iteration of a loop SYNOPSIS
continue _________________________________________________________________ DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code, which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as the catch command and the outermost scripts of procedure bodies. EXAMPLE
Print a line for each of the integers from 0 to 10 except 5: for {set x 0} {$x<10} {incr x} { if {$x == 5} { continue } puts "x is $x" } SEE ALSO
break(1T), for(1T), foreach(1T), return(1T), while(1T) KEYWORDS
