To use a formatting symbol, type the variable name followed by a comma and the
appropriate symbol. For example, if var has a value of 0x0065, and you want to
see the value in character form, type “var,c” in the Name column of the Watch
window. When you press Enter, the character format value appears: var,c = ‘e’.
Likewise, assuming that hr is a variable holding HRESULTs, view a humanreadable
form of the HRESULT by typing “hr,hr” in the Name column.
You can use the formatting symbols shown in the following table to format the
contents of memory locations.

With the memory location formatting symbols, you can type any value or expression
that evaluates a location. To display the value of a character array as a string,
precede the array name with an ampersand, &yourname. A formatting character
can also follow an expression:
• rep+1,x
• alps[0],mb
