The name of a database containing a field Variable which will be used to set Interchange variable values. For example, a database defined as:
Database var var.txt TAB VariableDatabase var
code Variable HELLO Hi!
would cause __HELLO__ to appear as Hi!.
The field name is case-sensitive, and variable would not work.
The values are inserted at time of definition. Any single-level hash-oriented Interchange directive, such as SpecialPage, ScratchDefault, or ValuesDefault, can be set in the same way. If the VariableDatabase named does not exist at definition time, a database of the default type with an ASCII file source appending .txt is assumed. In other words:
is equivalent to
Database variable variable.txt TAB VariableDatabase variable
