Loops within loops

You can't do stuff like: if [ $pnpanxx != $npanxx ] and [ $frange != T ]
Or at least it won't do what I'm guessing you think it might do. Try this:
if [ 1 = 1 ] and [ 99999 = 1 ] ; then
echo yes
fi
I don't understand how you can "kill the first loop process" and have it continue.

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
