Help for QB

Qb will sequentially display (using VIDS) files listed in an input text file.
Qb pauses after each display until the user enters a CR.  If QUIT is entered,
the proc will terminate.  It works for byte or halfword images.  It will 
zoom the image down to fit the screen or show as much as the screen can hold.

The input list is in SRCH format.  That is, the first record says :
NEXT FILE=0001.   Each subsequent record is a file spec.  However, SRCH 
need not be run to create the file.  A DCL DIRE/NOHEAD/NOTRAIL  file_spec
will make the list of file specs, but the first record must be added by 
editor.

Qb should be given its RANGE parameter if the data is halfword.  It will 
default to RANGE=(0,4095).

Example:

	qb input=A.LIS 
		images from text file A.LIS will be displayed zoomed to fit
                screen if necessary.

	qb input=A.LIS 'FULL
		no zooming done

	qb range=(0,4000) input=A.LIS 
		halfword images from file A.LIS will be compressed from
		0 to 4000 into 0 to 255 and zoomed if necessary.
