TO
Type:  Verb
Use:   In the FOR loop construction TO is used to seperate
       the starting value for the incrementing variable
       from the limiting value. (See FOR).
Grammar:  FOR variable = start TO fini BY increment
             statement1; statement2;... ; END
       where 'variable' is a scalar variable that will
       change each time through the loop, beginning at
       'start', have 'increment' added to it each time
       through the loop (the increment may be positive
       or negative) and will end when the loop has been
       executed with 'variable' greater than or equal to
       'fini'.  Note that this implies that the loop
       will be executed at least once no matter what the
       start, fini and increment parameters are.
       If the BY section is omitted, the increment
       will default to 1.  Statementi are AIPS statements.
Examples:  FOR I = 1 TO 10; SUM = SUM + A(I); END
           FOR I = K+3 TO K BY -1; A(I+1) = A(I); END
       In the first example SUM will be incremented by the
       sum of the first 10 elements in array A.
       The second example will shift the section of array
       A between A(K) and A(K+3) forward 1 element.
