Q. Explain the Traces debugging method?

Traces:-Printout contains merely certain memory and register contents and printing is conditional on some event occurring. Typical conditionings are exit, entry or use of-

1) A particular statement, macro, subroutine or database

2) Communication with a disk, terminal, printer or other peripheral

3) The value of a variable or else expression and

4) Timed actuations in definite real time system.

A special problem with draw programs is that the conditions are entered in the source language and any changes require a recompilation.
