The output mask used to present the formatted data value of a field in a list, report or output command.
Valid Values
The applicable masking pattern characters depend on the data type (Type) of the field (e.g., char, varchar, alpha, varalpha, numeric, int, longint, vastint, or date).
For a more detailed explanation of mask patterns and their relation to data types, see Masking.
Remarks
The FieldMask is used automatically unless an explicit mask has been applied:
- with the $mask function; or
- with the MASK format option in Zim Reports.
If FieldMask is $Null, the field will be output without masking unless only an explicitly programmed mask will be used, if provided.
The conditional expression that defines a relationship. The specific association between objects.
Valid Values
Any conditional expression
Remarks
Objects mentioned in the RelCondition should exist before the relationship is created. Referenced objects that do not exist when a RelCondition is created are interpreted as character strings if SET QUOTING is OFF.
For example,
Employees.DeptNum = Departments.DeptNum
defines a relationship between employees (in entity set Employees) and their departments (in entity set Departments) using a common department number (DeptNum).
The component structure of a named set.
Valid Values
A valid set specification, defining the component structure of the set
Remarks
Any objects mentioned in the set specification must exist before the named set is created.
The name assigned to a named set.
Valid Values
An 18-character string, containing a valid object name
See Also
ConstName, DDObjectName, DDOwnerName, DirName, DisplayName, DocName, EntName, FieldName, FormName, MenuName, OwnerName, RelName, RoleName, UserName, VarName
A user-assigned classification for a relationship.
Valid Values
A character string, up to 18 alphanumeric characters
The name assigned to a relationship.
Valid Values
An 18-character string, containing a valid object name
See Also
ConstName, DDObjectName, DDOwnerName, DirName, DisplayName, DocName, EntName, FieldName, FormName, MenuName, OwnerName, RoleName, SetName, UserName, VarName
The number of decimal places for numeric fields or variables.
Valid Values
Any integer.
If Decimals is left blank, 0 is used by default.
Remarks
Decimals is used for int, longint, vastint, and numeric data types and is ignored when the data type is date, alpha, varalpha, char, or varchar.

Length, Type
The name assigned to a role.
Valid Values
An 18-character string, containing a valid object name
See Also
ConstName, DDObjectName, DDOwnerName, DirName, DisplayName, DocName, EntName, FieldName, FormName, MenuName, OwnerName, RelName, SetName, UserName, VarName
The members of the owner-object associated with the role. An expression that indicates which members of the owner-object are represented by a role.
Valid Values
Any conditional expression involving fields from the owner-object only. If the role condition is omitted, the associated role name applies to all members of the owner-object.
Remarks
For example, a role called NYEmps whose owner is the Employees entity set might use the role condition:
Employees.Location = “New York”
The role NYEmps therefore refers only to those Employees that work in New York.
The default value for a field or form field. The value that a required field or form field will assume if no value is specified by the end-user.
Valid Values
A 256-character string, containing any character or numeric Valid Values
Remarks
Non-virtual Fields
Default should contain a value expression that will be evaluated and assigned to the field during an ADD command. If no expression is specified, and no value is assigned during an ADD, the field’s value is set to $Null.
Virtual Fields
A value expression that defines the virtual field’s contents must be specified.
Form Fields
If no expression is specified, the null string (“”) is used.
