       incr - Increment the value of a variable

       incr varName ?increment?

       Increments the value stored in the variable whose name is varName.  The
       value of the variable must be an integer.   If  increment  is  supplied
       then  its  value	 (which	 must  be an integer) is added to the value of
       variable varName;  otherwise 1 is added to varName.  The new  value  is
       stored  as  a  decimal  string in variable varName and also returned as

       Starting with the Tcl 8.5 release, the variable varName passed to  incr │
       may  be	unset, and in that case, it will be set to the value increment │
       or to the default increment value of 1.

       Add one to the contents of the variable x:
	      incr x

       Add 42 to the contents of the variable x:
	      incr x 42

       Add the contents of the variable y to the contents of the variable x:
	      incr x $y

       Add nothing at all to the variable x (often useful for checking whether
       an argument to a procedure is actually integral and generating an error
       if it is not):
	      incr x 0
