lookupall( -- builds a text array containing one item for every record in the target database where the data in the keyField matches the keyData. Each item in the text array contains the value extracted from the dataField for that record. If the data field is a numeric or date field, it is converted to text using the default patterns for that field.
lookupalldouble( -- is similar to the lookupall( function, but it returns two fields from the target database instead of just one.

Unlike the lookup( function which searches from the top of the database, the *lookuplast(* function searches backwards from the bottom.
lookuplastselected( -- searches the selected records in a database for a value, then returns other information from the same record. For example, the *lookuplastselected(* function can look up a phone number given a customer name, or look up a price given a part number. Unlike the lookupselected( function which searches from the top of the database, the *lookuplastselected(* function searches backwards from the bottom.
lookupmoredata( -- looks up an additional data field based on the previous lookup.
lookupmoreformula( -- looks up additional data based on a previous lookup.

setfieldnames -- changes the names of all database fields at once.
setfieldproperties -- modifies one or more properties (name, data type, formula, etc.) of the current field.

superarraybuild -- scans a database to create a text array. This statement is is similar to arraybuild, but with a number of additional options (see Text Arrays).
superlookup( -- searches a database for a record that matches a query formula, then uses a second formula to return other information from the same record. This is similar to the lookup( function, but instead of using an individual field for the key and data, any valid true/false (Boolean) formula can be used.
table( -- searches a database for a value, then returns other information from the same record. Unlike the lookup( function, the *table(* function does not require an exact match. If it does not find an exact match the *table(* function will use the closest match. For example, the *table(* function can look up a tax rate given an income amount, or look up a shipping price given a zip code and weight.
