The Origin Row and
Col fields combined with the
Last Row and
Col fields can be used to define the layout of the screen. Use negative values for the origin row of the bottom of the screen table to ensure they appear at the bottom of the screen even for different terminal sizes. If you want to have screen tables side by side, you must use the Last Row and Col attributes to specify the bottom right corner of the left screen tables.
Notice that in the following diagram there is wasted space below the SALES_SUMMARY screen table. This can be avoided by using negative numbers for the Last Row attribute. If the Last Row attribute for the SALES_SUMMARY screen table were set to -2 instead of 22, the screen table would expand to fill all the space in the 80x44 screen.
