DUMP                                                           DEBUG subcommand

Use the DUMP subcommand to print part or all of your virtual storage on the
printer.  First, a heading:
   ident FROM starting location TO ending location
is printed.  Next, the general registers 0-7 and 8-15, and the floating-point
registers 0-6 are printed, followed by the PSW, CSW, and CAW.  Then the
specified portion of virtual storage is printed with the storage address of the
first byte in the line printed at the left, followed by the alphameric
interpretation of 32 bytes of storage.

The format of the DUMP subcommand is:
+----------+------------------------------------------------------------------+
| DUmp     | [0|symbol1|hexloc1 [32|symbol2|hexloc2|*] [ident]                |
+----------+------------------------------------------------------------------+

where:

symbol1  is the name assigned (via the DEFINE subcommand) to the storage
         address that begins the dump.

hexloc1  is the hexadecimal storage location, in relation to current origin,
         that begins the dump.

symbol2  is the name assigned (via the DEFINE subcommand) to the storage
         address that ends the dump.

hexloc2  is the hexadecimal storage location, in relation to the current
         origin, that ends the dump.

*        indicates that the dump ends at your virtual machine's last virtual
         storage address.

ident    is any name (up to eight characters) that identifies the dump.
