Hammer & Screwdriver Unclear how you are stepping thru variables

Having trouble following your logic, but perhaps the following thoughts will help this move along:
(1) The variable "$#" will be the number of parameters supplied. Thus, perhaps no need for the first 3 after your command because you could skip this and then do NumberOfTables="$#"
(2) The shift function allows a script to keep processing references to $1. Thus, you would do your first set of commands and then do a shift. Shift moves what is in $2 to $1, $3 to $2, etc... ; what was in $1 is now gone.

__________________________________________________________________________________________________________________________________________________

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)
