The PRGRS_WAIT_DELAY switch allows you to determine the number of seconds you will allow the DataServer to delay further execution while waiting for the ODBC driver to respond to a request that may initiate a lock on a database resource. The delay is initiated when the NO-WAIT option is used in your ABL and the DataServer is awaiting a response to a database request made through the ODBC driver to MS SQL Server. The PRGRS_WAIT_DELAY switch is ignored unless you are running in ODBC asynchronous mode. Check your driver and OpenEdge connection requirements to determine if you are allowed to run in asynchronous mode.
