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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The Display Expression (?) command displays the value of a
     CodeView expression. The simplest form of expression is a symbol
     representing a single variable or function. An expression may also
     contain functions that are part of the executable file.
 
     The Display Expression command can also set values. For example,
     with the C expression evaluator, you can increment the variable n
     by using the following form of the command:
 
          ? n=n+1
 
     The command displays the new value after incrementing n.
 
     You can specify the format in which the values of expressions are
     displayed by the Display Expression command. Type a comma after
     the expression, followed by a CodeView format specifier.
