334		TIBXScript: runs an SQL script in the specified file or stream. The text is parsed
335		into SQL statements which are executed in turn. The intention is to be ISQL
336		compatible but with extensions:
337
338	<	* SET TERM and Set AutoDDL are both supported
338	>	* All DML and DDL Statements are supported.
339	>
340	>	* CREATE DATABASE, DROP DATABASE, CONNECT and COMMIT are supported.
341	>
342	>	* The following SET statements are supported:
343	>	SET SQL DIALECT
344	>	SET TERM
345	>	SET AUTODDL
346	>	SET BAIL
347	>	SET ECHO
348	>	SET COUNT
349	>	SET STATS
350	>	SET NAMES <character set>
351
352		* New Command: RECONNECT. Performs a commit followed by disconnecting and
353		reconnecting to the database.
#	Line 76 | Line 370 | type
370
371		* Database: Link to TIBDatabase component
372		* Transaction: Link to Transaction. Defaults to internaltransaction (concurrency, wait)
373	+	* AutoDDL: When true DDL statements are automatically committed after execution
374		* Echo: boolean. When true, all SQL statements are echoed to log
375		* StopOnFirstError: boolean. When true the script engine terminates on the first
376		SQL Error.
377		* IgnoreGrants: When true, grant statements are silently discarded. This can be
378		useful when applying a script using the Embedded Server.
379	+	* ShowPerformanceStats: When true, performance statistics (in ISQL format) are
380	+	written to the log after a DML statement is executed
381	+	* DataOutputFormatter: Identifies a Data Output Formatter component used to format
382	+	the results of executing a Select Statement
383
384
385		Events:
#	Line 95 | Line 394 | type
394		value of progress bar. Otherwise called to step progress bar.
395		* OnSelectSQL: handler for select SQL statements. If not present, select SQL
396		statements result in an exception.
397	+	* OnSetStatement: called to process a SET command that has not already been
398	+	handled by TIBXScript.
