Tokens Supported For System Delimiters

mvBase supports run-time efficient tokens called @AM, @FM, @VM and @SM for the attribute delimiter, the field delimiter, the value delimiter, and the sub-value delimiter, respectively.

Token Name	Delimiter	Value
@AM	Attribute mark	CHAR(254)
@FM	Field mark	CHAR(254)
@VM	Value mark	CHAR(253)
@SM	Subvalue mark	CHAR(252)

These new tokens may be used anywhere CHAR( ) may be used, including EQUATE statements.
