 *
 *	Tester.c can be taken both as a test program and as an example of usage,
 *	in spite of its cut and paste, overblown and ugly coding style, of usage
 *	for each of the "hdwrench.library" API entry points.
 *
 *	Functions:
 *		Support:
 *		1) Open device and close device
 *			BU baseunit.
 *		Translations:
 *
 *		2) Read RDB from <file>.list and write as mountfile to <file>..list.
 *		3) Read RDB from <file>.list and write as RDBs to <file>..rdb.
 *		4) Read RDB from <file>.rdb and write as mountfile to <file>..list.
 *		5) Read RDB from <file>.rdb and write as RDBs to <file>..rdb.
 *		6) Read Mountfile from memory and write as Mountfile to memory.
 *			(uses 000.list for input and writes to "foo" and screen.)
 *		7) Read Mountfile from memory and write as RDB Structs to memory.
 *			(uses 000.list for input and writes to "foo".)
 *		8)  Read RDBStructs memory and write as RDB Structs to memory.
 *			(uses 000..rdb for input and writes to "bar".)
 *
 *		Basic Disk acccesses:
 *		9) Read RDB from disk and write as mountfile to <file>...list.
 *		10) Perform SCSI Inquiry and report results up to 40 bytes.
 *		11) Perform SCSI ModeSense  and report results up to 255 bytes.
 *		12) Perform SCSI Read Capacity and report disk size.
 *		13) Perform SCSI Test Unit Ready and report device readiness.
 *
 *		Complex Disk Accesses...
 *		14) Find Disk Name returning in string variable.
 *		15) Find Controller self-ID returning in ULONG (which Commododo fails!).
 *		16) Report last available block on the drive.
 *		17) Generate default drive parameters.
 *		18) Read and report raw sector 'MS'.	(Not really complex but...)
 *		19) Find all valid disks on a given controller
 *
 *		Dangerous disk accesses:
 *		20) Raw write to a block of low disk. (Safe write - I hope!)
 *		21) Write with checksum to a block of low disk. (Safe write - I hope!)
 *		22) Read RDBs from <file.list> and write to disk. (The biggie!)
 *		23) Read RDBs from disk and write to RDBStructs to <file>.rdb.
 *		24) Read RDBStructs from <file>.rdb and write to <file>...rdb.
 *		25) Verify data on disk.
 *		26) Read RDBStructs from <file>...rdb and write to Disk.
 *		27) Read RDBs from disk and write RDB Structs memory thence to file
 *			 and console as hex.
 *		100) Format Drive - VERY DANGEROUS!
 *
 *		Presumes "scsi.device" else enter "DEVICE devicename".
