EFFECT
This function draws all structures "posted" on the workstation. The display
surface may or may not be cleared, depending on the value of the control flag
COFL. If the control flag is PCONDI, the display surface is cleared only if it
is not empty. If the control flag is PALWAY, the display surface is always
cleared.
Clearing the display surface of a printer or plotter often results in a blank
page being issued. For workstations of this type it is preferable to set the
control flag to PCONDI.
