1    /ALL

    Displays details of all call frames beginning at the current
    frame and continuing until bottom of stack (equivalent to SHOW
    CALL and repeated execution of a SHOW CALL/NEXT command).

2    /EXCEPTION_FRAME

       /EXCEPTION_FRAME=intstk-address

    (Integrity servers only) Provides an alternate starting address
    for SHOW CALL_FRAME. intstk-address is the address of an
    exception frame from which SDA creates an initial invocation
    context and displays the procedure call frame.

3    /NEXT_FRAME

    Displays the procedure call frame starting at the address
    stored in the frame longword of the last call frame displayed
    by this command. You must have issued a SHOW CALL_FRAME command
    previously in the current SDA session in order to use the /NEXT_
    FRAME qualifier to the command.

4    /SUMMARY

    Provides a one-line summary for each call frame, including
    exception frames, system-service entry frames, ASTs, KPBs, and
    so on, until reaching the bottom of the stack.
