Using the CDELAY operand of the &PANEL statement, it is possible to prevent output to a terminal in input mode being delayed, irrespective of the value of the SYSPARMS CDELAY operand. This is advisable in situations where output can affect the structure of a panel being displayed.
For example, members might be asynchronously inserted into a selection list while selections are being made by the operator. In this situation, the chosen selection variable may be associated with a certain entry before the list is updated and a associated with a different entry afterward. Specifying CDELAY=N synchronizes the arrival of the output with its appearance on the panel.
For more information about the CDELAY concept, see the Reference Guide.
