Each field in a copybook has a number of associated properties, or in XML Schema terms, facets. Some of these properties are defined in the Program I/O area (Type, Minimum OCCURS, and Maximum OCCURS); others are XML Schema properties.
The XML Schema properties do not exist in the copybook. They are additional properties that you can use to constrain the legal values for a field. For example, you can make the maximum length of a field smaller, but you cannot make it larger.
| Property |
Description |
| Client Access Rights |
Sets whether a client can view and/or update a specific field on the host. This can be used to hide data from users of client applications. To allow a client to both read and update the values for this field, select READ/WRITE. To allow the client only to view the value of this field, select READ. To hide this field from the client, select NONE. |
| Type |
(Read-only) Data type. This value cannot be modified. |
| Minimum OCCURS |
Set the minimum number of times this field must occur in the Program I/O area. Available when an ODO (object depending on) subject is selected. |
| Maximum OCCURS |
Set the maximum number of times this field can occur in the Program I/O area. The value for this property must be greater than or equal to the value for Min Occurs. Available when an ODO subject is selected. |
| Fixed OCCURS |
Set a fixed number of times this field occurs. Available when a field with OCCURS is selected. |
| Min Length |
Set the minimum length of this field in bytes. |
| Max Length |
Set the maximum length of this field in bytes. The value for this property must be greater than or equal to the value for Min Length.
 |
Changing the value for the maximum length of a field to a value larger or smaller than the length of the field on the host can result in errors when a task is run. This may cause the task to fail completely, or generate invalid data or results. |
|
| Default |
Specify a default value for the field. The default value for a field is sent to the host when a value is not received when the task is run. |
| Min Inclusive/Exclusive |
Select one. Min Inclusive is used in combination with Max Inclusive to restrict a value to a specified range; Min Exclusive is used in combination with Max Exclusive to restrict a value outside of a specified range. |
| Max Inclusive/Exclusive |
Select one. Max Inclusive is used in combination with Min Inclusive to restrict a value to a specified range; Max Exclusive is used in combination with Min Exclusive to restrict a value outside of a specified range. |
| Object of this OCCURS DEPENDING ON |
Specifies the object of this ODO clause. Available only when an ODO clause is selected. |
| Precision |
Specify the maximum number of decimal digits. This property must be applied to a positive integer. |
| Scale |
Specify the maximum number of decimal digits in the fractional part of a value. You cannot specify a number greater than the value for Precision. |
| Pattern |
A regular expression used to match the value of the field to a particular pattern.
|
Values specified for the pattern property do not get saved to the task file created. Although a value can be enetered, there is no support for patterns in this release. |
|
| Translate Field |
Specify whether to translate this field from PC code pages to EBCDIC (choose Yes or No). |
