- symField
- Type: Symbol
The symbolic name of the field in the database file structure for the current work area.
Return Value
Type:
Usual
The value of the specified field.
If
symField does not correspond to a field in the current database file, FieldGetSym() returns NIL.
Remarks
FieldGetSym() retrieves the value of a field using its symbolic field name within the database file structure, rather than the string representation of the field name.
Tip |
---|
FieldGetSym() can be used with a BLOB field (that is, a memo field associated with a BLOB file), provided the length of the field does not exceed 64KB.
For BLOB fields longer than 64KB, use the BLOBGet() function instead.
