Remarks

The .echo command causes the debugger to display String immediately after you enter the command.

An .echo command is ended if the debugger encounters a semicolon (unless the semicolon occurs within a quoted string). This restriction enables you to use .echo in more complex constructions such as with the j (Execute If - Else) command, as the following example shows.

0:000> j (poi(MyVar)>5) '.echo MyVar Too Big'; '.echo MyVar Acceptable;

The .echo command also provides an easy way for users of debugging servers and debugging clients to communicate with one another. For more information about this situation, see Controlling a Remote Debugging Session.

The .echo command differs from the $$ (Comment Specifier) token and the * (Comment Line Specifier) token, because these tokens cause the debugger to ignore the input text without displaying it.
