You can invoke LSE in either of the following two ways:

    o  To use LSE within interactive SQL, define the logical names
       SQL$EDIT and LSE$ENVIRONMENT:

       $ DEFINE SQL$EDIT LSE
       $ DEFINE LSE$ENVIRONMENT -
       _$ SYS$COMMON:[SYSLIB]LSE$SYSTEM_ENVIRONMENT.ENV

       Then, when you enter the EDIT statement from within SQL, you
       automatically invoke LSE with SQL templates.

    o  To invoke LSE from DCL level, type LSE followed by the name
       of the file you want to edit. The file type determines
       the templates that LSE uses. To invoke the templates for
       interactive SQL, use the file type of SQL; to invoke the
       templates for SQL module language, use the file type of
       SQLMOD. For example, you can type the following commands:

       $ LSE SAMPLE.SQL

       or

       $ LSE SAMPLE.SQLMOD
