WSQL Examples: Request Data
                  Request Column_Names
                  Request Column_Names_And_Data
VX-REXX Examples: value = VRMethod("DDEC_1", "Request", item, [type]) or
                      status = VRMethod("DDEC_1", "RequestList", item, "value.")
Requesting data gives the calling application a block of memory containing the requested data, as opposed to placing the data on the clipboard for the application to access.
WSQL DDE Server only supports cold request links - this rules out using the ACKNOWLEDGE event for VX-REXX. WSQL DDE Serverplaces the results of the query currently in the query buffer into a memory block and then sends the address of the memory to the application.
