Use this command to display and modify memory locations. The command does not
verify memory contents after they are stored.  After entering the command, it
prompts you with the current contents of a memory location.

The different display and edit formats supported are:
•  bytes
•  words
•  floating-point numbers
•  scientific format
•  double-precision numbers

−  hexadecimal format
−  hexadecimal format

When the contents of the memory location appear, type:
•  a new value to store at the location
•  a hyphen (-) to back up one location
•  a plus sign (+) or the 

ENTER

 key to move forward one location (CCU / D25 only)

•  a period (.) to exit this function

Scientific values must subscribe to the following format:

[±] mantissa [e [±] exponent]

The mantissa can contain a decimal point. This command differentiates between a
negative number and a hyphen.
