Important Notice
The pages on this site contain documentation for very old MS-DOS software,

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out of date.

◄At Location/Expression Changed► ◄Keyboard► ◄Up► ◄Contents► ◄Index► ◄Back►
────────────────────────────────────────────────────────────────────────────
1. Click Break at Location if Expression has Changed.
2. Click in the Location box. Type the location at which you
want to set the breakpoint. CodeView checks for changes in
the expression only at this location in the program.
3. Click in the Expression box and type an expression that
evaluates to an address. The expression can be an address in
the form of <segment>:<offset>, or it can be an expression
involving variables in your program.
4. If you want execution to break when a range of memory changes,
click in the Length box and type the size of the range. The
range is the number you type multiplied by the size of the
expression you are watching.
5. If you want CodeView to pass over the breakpoint a given
number of times, click in the Pass Count box. Type the number
of times to pass over the breakpoint.
6. If you want CodeView to execute commands after execution
breaks, click in the Commands box. Type the commands you want
to execute.
7. Click <OK>.
