Destroying a control

When a control is no longer necessary, it should be destroyed. All the resources used by that control are released.

The syntax of the DESTROY Statement is:

Format 1

DESTROY {screen-name-1 } ... {handle-1 } {CONTROL AT location}

location is defined as follows:

{ screen-loc [CELL ] [CELLS ] [PIXEL ] [PIXELS]     LINE NUMBER line-num [CELL ] [CELLS ] [PIXEL ] [PIXELS]   {COLUMN } NUMBER col-num [CELL ] {COL } [CELLS ] {POSITION} [PIXEL ] {POS } [PIXELS] }

Format 2

DESTROY ALL CONTROLS

Format 3

DESTROY {window-handle }

Destroying every single control may be slow, the best approach is to destroy the whole Screen in which controls are defined. When a graphical window is destroyed, all controls associates to the window are automatically destroyed. The main application Window can't be destroyed.
