User Variables 5-19

5-19

The native data type (Real, Text, etc.) is always included in the

list of active filters. It cannot be deleted. To include a newly

created filter name with the active filters, highlight the filter

name on the right and click the Add button. To remove a filter

from the active list, click the Remove button.

5.6.4 Security Tab

There are two levels of User Variable protection available on the

Security tab. The two levels are split into two groups on the tab:

• Password to Edit/Delete

•Variable

Password to Edit/Delete Group

When you have assigned a password, you are required to enter

that password before the variable can be edited or deleted. As a

convenience, if the password is entered correctly when

requested it is not requested again until the next time the case

is opened. However, you are always required to enter the

password if you are attempting to delete a User Variable.

Combining a password with the Automatic attribute would

guarantee that a User Variable is always present in any instance

of its owning object.

Filtering can only be applied using the drop-down list of the

User Variable page of Unit Operation property views.

Figure 5.18

A suitably cryptic variable Tag is highly recommended when

using a password in order to protect against programmatic

access to the variable.
