Comments The order of fields is as listed in the datafields field of the
Queries
table.
Example 1: Three fields are listed in datafields . When a record is picked from the list,
the three fields are echoed back to the system using the Data1, Data2, and Data3
signals.
However, note that only fields defined by the data filter bit pattern are sent. (See
DataFilter for more information.)
When using successive queries (Successive query checked in the Scroller Signal
Block Definition window ), all the list fields listed in the listfields field of the
Queries
table are echoed using the first (so many) Data signals. Only the last list
in the successive query is actually considered to be a “pick” (record opener). When
the record is finally picked, the fields listed in the
datafields field of the
Queries
table are transmitted using the remaining Data signals.
Example 2: If there are three lists consisting of 1, 3, and 2 list fields, then these fields
are echoed using the {
Data1 }, { Data2 , Data3 , Data4 }, and { Data5 , Data6 } signals.
Upon picking an item from the third list, a record is opened and the fields listed in
datafields (say in this case there are three such fields listed) are echoed using the
{ Data7 , Data8 , Data9 } signals.
All Data signals in a successive query are subject to filtering. (Again, see
DataFilter for more information.)
