deferred class Generator from ExprIntrp inherits TShared from MMgt

	---Purpose: Implements general services for interpretation of 
	--          expressions.

uses NamedExpression from Expr,
    NamedFunction from Expr,
    SequenceOfNamedFunction from ExprIntrp,
    SequenceOfNamedExpression from ExprIntrp,
    AsciiString from TCollection
