The .echo command displays a comment string.

If you do not enclose String in quotation marks, it can include quotation marks in any location except the first character, but it cannot include semicolons.

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 complex constructions such as conditional breakpoints, as the following example shows.


0:000> bp `:143` "j (poi(MyVar)>5) '.echo MyVar Too Big'; '.echo MyVar Acceptable; gc' " 

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.
