	Name	Description
	Decimals	A numeric value representing the number of decimals defined to this field specification. (Inherited from FieldSpec.)
	HyperLabel	The hyperlabel connected to this field specification. (Inherited from FieldSpec.)
	Length	A numeric value representing the length defined to this field specification. (Inherited from FieldSpec.)
	Maximum	A numeric value representing the maximum value in the range validation for this field specification. (Inherited from FieldSpec.)
	Minimum	A numeric value representing the minimum value in the range validation for this field specification. (Inherited from FieldSpec.)
	MinLength	A numeric value representing the new minimum length validation for this field specification. (Inherited from FieldSpec.)
	MinLengthHL	Error message when MinLength validation fails. (Inherited from FieldSpec.)
	Nullable	Is the field Nullable ? (Inherited from FieldSpec.)
	Picture	A string representing the picture clause defined to this field specification. It is used by the FieldSpec:Transform() method. (Inherited from FieldSpec.)
	RangeHL	Error message when Range validation fails. (Inherited from FieldSpec.)
	Required	Logical value indicating whether the field is required (TRUE) or not (FALSE). (Inherited from FieldSpec.)
	RequiredHL	Error message when Required validation fails. (Inherited from FieldSpec.)
	Status	After a validation request (see FieldSpec:PerformValidations() for details), this contains a HyperLabel object that describes the results of the validation or NULL_OBJECT if the validation passed. (Inherited from FieldSpec.)
	UsualType	A constant, representing the data type defined to this field specification: (Inherited from FieldSpec.)
	Validation	A code block that sets the validation rule for this field specification. (Inherited from FieldSpec.)
	ValidationHL	Error message when Validation fails. (Inherited from FieldSpec.)
	ValType	A one-character string representing the data type defined to this field specification: (Inherited from FieldSpec.)

Methods

	Name	Description
	AsString	Return the caption defined to this field specification's hyperlabel; if no caption is defined, return the name defined to the hyperlabel. (Inherited from FieldSpec.)
	PerformValidations	Test a specified value to see if it passes all of this field specification's validation rules. (Inherited from FieldSpec.)
	SetLength	Set a new length for this field specification and new hyperlabel diagnostics for the length check. (Inherited from FieldSpec.)
	SetMinLength	Set a new minimum length validation for this field specification and new hyperlabel diagnostics for the minimum length check. (Inherited from FieldSpec.)
	SetRange	Set a new range validation for this field specification and new hyperlabel diagnostics for the range check. (Inherited from FieldSpec.)
	SetRequired	Set a new required validation for this field specification and new hyperlabel diagnostics for the required check. (Inherited from FieldSpec.)
	SetType	Set a new data type for this field specification and new hyperlabel diagnostics for the data type check. (Inherited from FieldSpec.)
	SetValidation	Set a new validation rule for this field specification and new hyperlabel diagnostics for the validation rule check. (Inherited from FieldSpec.)
	Transform	Convert a specified value into a string, formatted according to this field specification's picture clause. (Inherited from FieldSpec.)
	Val	Convert a string to a value, according to this field specification's defined data type. (Inherited from FieldSpec.)
	Validate	A replaceable method for performing validations. The standard implementation evaluates the code block specified through FieldSpec:SetValidation(). (Inherited from FieldSpec.)
