Value Checking
Value checking is a method of tracing the value of variables in your assembly language program
using the interactive capabilities of the 9835A/ B. You already have been introduced to break
points and dumps in earlier sections. The capability of value checking serves as a useful adjunct
to these procedures.
The value checking of assembly "variables" is similar to the monitoring of variables in BASIC
during a debugging phase. Just as you would use a live-keyboard operation or judiciously
placed PRINT statements to trace the execution of a program or the change in value of a
variable in a BASIC program, so too can you use the monitoring tools for assembly programs.
