Create a Interbase database at runtime

Hi

I've found no way to  create a Interbase-database at runtime. Using ISQL
with

  CREATE DATABASE "myDatabase.gdb"
  USER "sysdba" PASSWORD "masterkey";

works fine. When I try to execute this statetment at runtime , I get
somthing like a "chicken and egg" problem. To execute a SQL-statement I
have to connect a Database but the only way (I know) to create a database
by SQL is executing the statement above.

Thank's in advance
