Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     Memory operators return the content of specific locations in
     memory. They are unary operators that return the result of a
     direct memory operation. Use these operators to debug in Assembly/
     Mixed mode; however, they are not needed for high-level debugging.

     Operator     Action
 
     BY           Accesses the byte at a given address. The result
                  is a short integer that contains the value of the
                  first byte stored at <address>.
 
     WO           Accesses the word at a given address. The result is a
                  short integer that contains the value of the first two
                  bytes stored at <address>.
 
     DW           Accesses the doubleword at a given address. The
                  result is a long integer that contains the value of
                  the first four bytes stored at <address>.
                  NOTE: Do not confuse the DW operator with the
                        Dump Words (DW) command.

     The CodeView memory operators are part of the C expression
     evaluator and should not be confused with CodeView commands. These
     operators have the lowest precedence of any C operators.
