@OP, in my opinion, this construct is better. You don't have to "clutter" the while loop conditions.

Code:
while [True];
do
     if condition1 is true { break }
     if condition2 is true {break } 
     do_something...
done

NAME
break - Abort looping command SYNOPSIS
break _________________________________________________________________ DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_BREAK code, which causes a break exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command, which then aborts its execution and returns normally. Break exceptions are also handled in a few other situations, such as the catch com- mand, Tk event bindings, and the outermost scripts of procedure bodies. EXAMPLE
Print a line for each of the integers from 0 to 5: for {set x 0} {$x<10} {incr x} { if {$x > 5} { break } puts "x is $x" } SEE ALSO
catch(1T), continue(1T), for(1T), foreach(1T), return(1T), while(1T) KEYWORDS
