The following qualifiers affect what happens at a routine call:

       /INTO
       /OVER
       /[NO]SHARE
       /[NO]SYSTEM

 The following qualifiers affect what output is displayed when a
 tracepoint is reached:

       /[NO]SILENT
       /[NO]SOURCE

    The following qualifiers affect the timing and duration of
    tracepoints:

       /AFTER:n
       /TEMPORARY

    Use the /MODIFY qualifier to monitor changes at program locations
    (typically changes in the values of variables).

    If you set a tracepoint at a location currently used as
    a breakpoint, the breakpoint is canceled in favor of the
    tracepoint, and conversely.

    Tracepoints can be user defined or predefined. User-defined
    tracepoints are set explicitly with the SET TRACE command.
    Predefined tracepoints, which depend on the type of program you
    are debugging (for example, Ada or multiprocess), are established
    automatically when you start the debugger. Use the SHOW TRACE
    command to identify all tracepoints that are currently set. Any
    predefined tracepoints are identified as such.

    User-defined and predefined tracepoints are set and canceled
    independently. For example, a location or event can have both
    a user-defined and a predefined tracepoint. Canceling the user-
    defined tracepoint does not affect the predefined tracepoint, and
    conversely.
