Table


Table ( tableNum \| aPtr ) -> Function result

Parameter	Type	Description
tableNum \| aPtr	Longint, Pointer	Table number, or Table pointer, or Field pointer
Function result	Longint, Pointer	Table pointer, if a Table number is passed Table number, if a Table pointer is passed Table number, if a Field pointer is passed

The Table command has three forms:

If you pass a table number in tableNum, Table returns a pointer to the table.
If you pass a table pointer in aPtr, Table returns the table number of the table.
If you pass a field pointer in aPtr, Table returns the table number of the field.

This example sets the tablePtr variable to a pointer to the third table of the database:

TablePtr:=Table(3)

Passing tablePtr (a pointer to the third table) to Table returns the number 3. The following line sets TableNum to 3:

TableNum:=Table(TablePtr)

This example sets the tableNum variable to the table number of [Table3]:

TableNum:=Table(->[Table3])

This example sets the tableNum variable to the table number of the table to which the [Table3]Field1 field belongs:

TableNum:=Table(->[Table3]Field1)
