{ PURPOSE:
{   The purpose of this procedure is to process the command VEDISPLAY that
{   is entered by the operator.
{
{       OFP$VEDISPLAY_COMMAND (PARAMETER_LIST, STATUS);
{
{   PARAMETER_LIST: (input) This parameter contains the parameter list as
{     supplied by SCL when processing any command. It contains the display
{     type and the output file name.
{
{   STATUS: (output) This parameter specifies the request status.  A normal
{     status value will be returned to indicate that no error occurred while
{     processing the command.  An abnormal status indicates that an error
{     was detected in the processing of the command.  Since the display will
{     continue to execute after the command is terminated the status variable
{     will not reflect any errors that occur while the display processor is
{     executing.
