Syntax options:

       LIST
       NOLIST

    Oracle Rdb determines whether or not the SQL precompiler
    generates a list file (default file extension .lis) that contains
    information about the SQL compilation and the host language
    compilation. In addition, if the logical name SQL$KEEP_PREP_FILES
    is defined, the SQL precompiler retains an intermediate module
    list file (file extension .mli), which contains information about
    the SQL compilation only. If you specify the LIST qualifier and
    do not include a file specification, the SQL precompiler creates
    a list file with the same file name as your source file with the
    file extension .lis.

    The NOLIST qualifier is the default.
