*SETIWALL (IMAGE)
*SETIWALL={top}:{bottom}:{left}:{right}
The image display routines normally attempt to define the image window as the currently active text sub-window. This may be overridden by using the *SETIWALL list control to specify the top, bottom, left and right image coordinates. The coordinates are given in terms of columns and rows. 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, as opposed to the *SETSWALL for DISPLAY and KEYIN instructions that stays in effect beyond the current instruction.
