*SETIWALL (IMAGESCAN)

*SETIWALL={top}:{bottom}:{left}:{right}

The image scan routines normally attempt to define the image window as the full page. This may be overridden by using the *SETIWALL list control to specify the top, bottom, left and right image coordinates. The coordinates (that may be decimal constants or numeric variables) are given in inches with as many as two (2) decimal places allowed. Fractional values may be specified when using numeric variables but not when using numeric literals.

This list control is only in effect for the current instruction. Note that the *SETSWALL control for DISPLAY and KEYIN instruction stay in effect beyond the current instruction.
