Library /sys$common/syshlp/lse$menu.hlb SET_ADJUSTMENT_PREFIX_INDENTATION  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Syntax:  SET ADJUSTMENT PREFIX INDENTATION indentation_value
              defined_adjustment defined_language

  Lets you skip a pattern at the beginning of a line to determine the
  indentation value.
