Symbolic forms can be used for the address. They are:

The program counter. The address space is set to GPR.

The location immediately following the last location referenced in a

deposit or examine command. For physical and virtual memory,

the referenced location is the last location plus the size of the

reference (1 for byte, 2 for word, 4 for longword). For other address

spaces, the address is the last referenced address plus 1.

The location immediately preceding the last location referenced in a

deposit or examine command. Memory and other address spaces

are handled as above.

* The last location referenced in a deposit or examine command.

@ The location addressed by the last location referenced in a deposit

or examine command.

The deposit command stores data in the location specified. If no options are given

with a deposit command, the system uses the options from the preceding deposit

command.

If the specified value is too large to fit in the data size listed, the console ignores

the command and issues an error response. If the data is smaller than the data

size, the higher order bits are filled with zeros. The syntax is shown below.

The examine command displays the contents of a memory location, a register, or

a device.

If no options are given with an examine command, the system uses the options

from the preceding examine command. If conflicting address space or data sizes

are specified, the console ignores the command and issues an error.

For data lengths longer than a longword, each longword of data should be

separated by a space.
