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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     To set a breakpoint when a symbol changes, enter a Breakpoint Set
     (BP) command of the form
 
          BP = symbol
 
     To watch a memory range for changes, enter a BP command of the form
 
          BP = symbol #range
 
     The size of the range watched for changes is the <range>
     multiplied by the size that the <symbol> represents. For example,
     in the expression
 
          BP = int_value #8
 
     if int_value is 2-byte value, the watch range is 16 bytes.
     Similarly, if int_array is an array of 10 integers, then
 
          BP = int_array [0] #10
 
     watches for changes in int_array, and
 
          BP = int_array #10
 
     watches for changes in the 200 bytes starting at the first element
     of int_array.
