Function FieldGet() Foundation
Determines the value of a field in the current record of a work area.
FieldGet( <nFieldPos> ) --> xValue
The return value of FieldGet() is the current value of the field at the position <nFieldPos> in the work area. When <nFieldPos> is not a valid field position in the work area, NIL is returned.
The database function FieldGet() reads the values of individual fields into memory. If the function is used without the alias operator, the value from the current work area is returned. FieldGet() allows access to records without requiring knowledge of the data structure (or the field name) since the field is specified only as a numeric field position. General input/output routines which are independent of a data structure can be programmed using this function.
