Library /sys$common/syshlp/dbg$help.hlb DEBUG, SET, STEP, Examples  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    1.DBG> SET STEP INSTRUCTION,NOSOURCE

      This command causes the debugger to execute the program to the
      next instruction when a STEP command is entered, and not to
      display lines of source code with each STEP command.

    2.DBG> SET STEP LINE,INTO,NOSYSTEM,NOSHARE

      This command causes the debugger to execute the program to
      the next line when a STEP command is entered, and to step into
      called routines in user space only. The debugger steps over
      routines in system space and in shareable images.
