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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.
Watchpoint Command
Use to suspend program execution when a condition you
specify becomes true. The condition may be:
  ■ A variable name
  ■ A relational statement
 
A relational statement is constructed using the operators
=, <>, >, <, >=, or <=.
 
If you use the simpler form and just enter a variable name
or an expression, the QBX environment assumes the
relation <> 0. For example, entering X + Y yields the
expression X + Y <> 0.
 
Add Watch:
    ■ Displays the values of variables as they change
      during program execution
    ■ Does not suspend program execution
A Watchpoint:
    ■ Does not display variables' values
    ■ Suspends program execution when the expression
      becomes true
