The "Exclude" button allow you to exclude any control from the window to be printed.
When you press the button a list with the current controls from the window pops up. In that list, you just select the ones that you don't want to print, and they are excluded from the output.
See the examples String and prompts with graphics and tabs and Drawings with tabs.
"From equate number" and "To equate number" below allow you to exclude a run-time created range of controls. Just enter a "From" field equate number and a "To" field equate number to exclude the whole range. If you only enter the "From" number only that control will be excluded.
