DISP

Rebuilds the screen image, and writes it to the terminal.

This is useful if a macro wishes to update the IDF user interface display, but continue running. Normally the rebuild and screen update does not occur until the macro completes execution.

NODISP

Rebuilds the screen image, but does not write the updated image to the terminal.

This is useful if a macro has issued a command which causes an update of the IDF user interface display, and needs to issue EXTRACT commands for the new display image. Eliminating the extra terminal update speeds up the execution of the macro.

This facility can even be used to hide the update by immediately issuing more commands to restore the user interface display to the previous configuration.

The REFRESH command can also be used to restore the IDF user interface display. This is normally only needed in a macro that sends line mode output to the screen, and should only be needed on TSO.
