pointname
startpt

steppt
Typical Examples
FOR loopcount = 0 TO 100
Ellipse_1.vertical%fill = loopcount
NEXT
In this example, 'Ellipse_1' is gradually filled 100 times.
FOR loopcount = 100 TO 0 STEP -5
Ellipse_1.vertical%fill = loopcount
NEXT
In this example, the fill for 'Ellipse_1' is gradually removed 20 times (100 times/-5).
Note: Loop statements should be used with caution, as they consume processor time while
they are running and some other parts of the system may not be updated.

CHAPTER 4 – CX-Supervisor Script Language
The pointname to be used as the loop counter.
The initial setting of pointname, and the first value to be used through the
loop.
The last value to be used. The loop ends when pointname exceeds this value.
Amount to increase pointname by every pass of the loop. Steppt can be
negative to count backwards providing startpt is larger than endpt. The STEP
keyword and variable may be omitted in which case pointname is
incremented at each pass of the loop (identical to adding STEP 1).
