an automatic conversion to “a”.
&xxxx&
Placeholder for an optional character from a set of characters. The list is placed between two “&”.
(@#
Placeholder for a mandatory letter from @ to # included.
If, the case of @ and # is different so the case is ignored
or else the case is active.
/
Placeholder for date separator.
:
Placeholder for time separator.

for display and value.
!
Formatting must proceed from right to left.
“all characters between” are only displayed (not present in the value).
If a format has an exponent, digits, and number separators with a decimal separator (and only one) then the format is a float format. The float format ignores placeholder <!>. The integer part reads from right to left while the decimal part reads from left to right. The other characters which are not between double-quotes, are displayed and included in the value.
Default Value
The default value is space for characters that are not mandatory characters.
