DV 
DEBUG command 
Privileged Mode Only 

Displays a requested number of sectors of virtual memory or disc,

SYNTAX 

         DV [ ldev + startsector[, count] [, mode]

PARAMETERS 

ldev             The logical device number of the disc to be displayed.
                 If omitted, the system disc is specified by default.
                 (Optional parameter.)

startsector      An expression signifying the starting sector address to
                 be displayed.  If the sector address requires more than
                 16 bits, it must be entered in the following form:

                  *  low-order bits:  high-order bits (Required
                     parameters.)

count            An expression indicating the number of sectors to be
                 displayed.  If omitted, one sector is displayed.
                 (Optional parameter.)

mode             One character to indicate representation mode of output
                 values:  0 for octal, I for decimal, or A for ASCII. If
                 omitted, octal output is assumed (Optional parameter.)

EXAMPLES 

     ?DV2 + 2230,5 

Displays 5 sectors from logical device number 2 starting at sector number
2230.

     ?DV+12345:3 

Displays 1 sector from the system disc starting at sector number 61234 5
(octal; bit pattem 110 001 010 011 100 101) where the low-order bits are
012345 (octal; 0 001 010 011100 101 in binary) and the high-order bits
are 3 (octal; 11 in binary).
