CHANGE ITEMSECURITY
Changes user class access to a data item.
Syntax
{R}
CHA[NGE] ITEMSE[CURITY] DataItemName UserClassNumber {W}
{N}
Parameters
DataItemName is the name of a data item whose security is to be
changed.
UserClassNumber is a user class number defined in the PASSWORD part
of the schema. User class numbers are used in the
schema security lists to define access to each data
set and data item.
R allows read-only access to the data item.
W allows write access (and implied read access) to the
data item.
N denies any access to the data item.
Description
Use this command to change user class access to a data item. To deny all
users access, create a null (or empty) list (/), which allows only the
creator access to the data item. When making changes to data item
security, remember that access to data items within data sets may be
further allowed or restricted by data set security.
Example
>change itemsecurity quantity 18 w
>change itemsecurity quantity 14 r
>change itemsecurity credit-rating 14 n
In this example, user class 18 is given write access to the data item
QUANTITY. User class 14 is given read access to the data item QUANTITY
and is denied any access to the data item CREDIT-RATING.
