I guess that the problem is due to the [[ ]] in the rotate function.
You need cat_while_read_LINE to return true (0) for the while loop to continue and false (non 0) for the while loop to terminate. No square brackets are needed.

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(3tcl), for(3tcl), foreach(3tcl), return(3tcl), while(3tcl) KEYWORDS
continue, iteration, loop Tcl continue(3tcl)
