10.6 String Tables - Incrementing Values in a String
In this exercise, you will define a simple string that displays three
images in three consecutive frames, use the
REPEAT command to define values for the string, and run
the string.
- Create a string called DISPLAY that displays images on frames.
- Type: TE DISPLAY "IMGDISP GV4.!1 !2 STA=DCA
The exclamation point (!) indicates the value will be defined and
incremented when you use the REPEAT command.
In this example, the dataset position number (!1) and the frame number (!2)
will increment.
- Repeat the DISPLAY string three times, starting at GV4 dataset position
1 and frame 4, and increase each value by one until dataset position 3 is
displayed in frame 6.
- Type: REPEAT DISPLAY 1 TO 3 BY 1 4 BY 1
- Set the loop bounds to frames 4 through 6 and loop the frames.
Stop looping.
- Type: LS 4-6
- Press: Alt L
- Exit McIDAS
- Type: EXIT
