C.1 DEC Language-Sensitive Editor (LSE) and Source
          Code Analyzer (SCA)
  The DEC Language-Sensitive Editor (LSE) and the Source
  Code Analyzer (SCA) must be purchased separately. LSE is
  a powerful and flexible text editor designed specifically for
  software development. LSE has important features that help
  you produce syntactically correct code in BASIC. SCA is an
  interactive tool that is used to perform program analysis.

  LSE and SCA are closely integrated products; generally, SCA
  can be invoked through LSE. LSE provides additional editing
  features that make SCA program analysis more efficient. In
  addition, LSE and SCA, in conjunction with the BASIC com-
  piler, provide a set of new enhancements supporting source
  code designing and review.

  For more information about LSE and SCA, see the Guide to
  Language-Sensitive Editor for VMS Systems and Guide to
  Source Code Analyzer for VMS Systems .
