Help for INSERT


 PURPOSE:

 ARTIFICIAL LINES IN A PICTURE AND RESCALE THE
 REMAINING LINES DOWN THE APPROPRIATE AMOUNT. INSERT
 IS USEFUL FOR CORRECTING MISREGISTRATION DUE TO
 LINE DROPOUT.

 EXECUTION:
 THE FOLLOWING IS THE EXECUTION STATEMENT FOR INSERT:
        insert  INP  OUT  PARAMS
 EXAMPLES:
 insert INP=A OUT=B SIZE=(1,1,100,200) LINE=(1,10)

 LINES 1 AND 10 OF THE OUTPUT DATA SET B ARE ARTIFICIALLY
 GENERATED BY AVERAGING PIXELS IN ADJOINING LINES.  LINES
 2 THROUGH 9 ARE LINES 1 THROUGH 8 OF THE INPUT DATA SET.
 LINES 11 THROUGH 102 ARE LINES 9 THROUGH 100 OF THE INPUT
 DATA SET.

 insert INP=A OUT=B SIZE=(1,1,100,200) DN=128 LINE=5 TRUNC=TRUNC

 LINE 5 OF THE OUTPUT DATA SET, B, WILL BE ARTIFICIAL WITH DN
 OF 128.  LINES 1 THROUGH 4 ARE LINES 1 THROUGH 4 OF THE
 INPUT DATA SET, A.  LINES 6 THROUGH 100 ARE LINES 5 THROUGH 99 OF
 THE INPUT DATA SET, A.
 RESTRICTIONS:

 MAX. NUMBER OF LINES THAT CAN BE INSERTED = 100.

 IF NO LINES ARE SPECIFIED FOR INSERTION THE INPUT
 DATA SET IS COPIED TO THE OUTPUT DATASET.  IF AN
 UNEXPECTED EOF OCCURS, ARTIFICIAL LINES ARE
 ADDED TO MAKE UP THE DIFFERENCE.
