PWD (Present Working Directory)

	PWD (Present Working Directory)
Query	:MMEMory:PWD? [<msus>]
	The PWD query returns the present working directory for the specified drive.
	If the <msus> option is not sent, the present working directory will be
	returned for the current drive.
Returned Format	[:MMEMory:PWD] <directory>,<msus><NL>
<directory>	String of up to 64 characters with the backslash (\) as separator for DOS and
	LIF disks.
<msus>	Mass Storage Unit specifier. INTernal0 for the hard disk drive and
	INTernal1 for the flexible disk drive.
