Tracing Tips

  1. When a loop is being traced, the DO clause itself is traced on every iteration of the loop.
  2. You can retrieve the trace actions currently in effect by using the TRACE built-in function (see section TRACE). function.
  3. If available at the time of execution, comments associated with a traced clause are included in the trace, as are comments in a null clause, if you specify TRACE A, R, I, or S.
  4. Commands traced before execution always have the final value of the command (that is, the string passed to the environment), and the clause generating it produced in the traced output.
  5. Trace actions are automatically saved across subroutine and function calls. See the CALL instruction (page Purpose) for more details.
