Installation
------------

	Copy the main program sqldb/db to a directory in your executable path.
	Add the assignment SQLDB: to your startup-sequence and have it point
	to a central location for your tables.

	In SQLDB:, create a file called lock_file.  It just has to exist.

	Make sure that your stack is set to 30000!!  Add 25000 or so for each
	level of subquery that you intend to use.

Getting Started
---------------

	Command-line options to SQLdb:

	Option	Arguments	Default		Meaning
	------	---------	-------		-------
	-t	'd' or 'r'	'r'		Temporary table storage
	-s	none		NA		Server mode


	Temporary Tables

	Temporary table are created whenever you give SQL a select query to
	perform.  The -t option allows you to specify where you wish the 
	temporary tables to be stored.

	The 'r' argument specifies that temporary tables are to be stored in
	main memory.

	The 'd' argument specifies that temporary table are to be stored in
	the current directory from which SQLdb was started from.

	Server Mode

	When started up in Server Mode, SQLdb will open up an ARexx port and
	await commands from the port.
