• "\" (causes the subsequent character to be displayed as a literal). For
example, the edit mask "\A" would display a parameter value of "A."
If the edit mask is "00\A00," then a valid parameter value would consist
of two digits, the letter "A," and then two additional digits.
• "Password". Allows you to set the edit mask to "Password," you can
create conditional formulas specifying that certain sections of the report
become visible only when certain user passwords are entered.
Note:
Some of the edit mask characters require that you enter a character in
their place (when entering a parameter value), while others allow you to
leave a space, if needed. For example, if the edit mask is 000099, you
can enter a parameter value with four digits, five digits, or six digits, since
the '9' edit mask character does not require the entry of a character.
However, since '0' does require such an entry, you could not enter a
parameter value with less than four digits.

Creating a saved-data record filter using parameter
fields
You can design your report so that users can filter fields and records without
refreshing information from the database. Saved-data record filters combine
the use of saved data selection formulas and the Parameter Panel.
This feature is particularly useful for several reasons:
• It allows users to filter and re-filter report data without leaving the canvas
of the report.
• It eliminates processing demand on the database.
• It reduces the time users spend waiting for data to be filtered.
• It allows users to filter records in the report even if they do not have a
connection or rights to access the database at the time of viewing.
When planning to include a saved-data record filter in your report, it is
important to consider the following points:
• To prevent report refreshing to the database, only non-data parameters
should be added to the Parameter Panel.
