A number of problems have been fixed in I64 BASIC V1.8-004. The
    known problems that have been fixed include:

    o  A dump was getting generated when the program was trying to
       perform copy in an optimized mode. This issue has been fixed.

    o  Extremely long command lines no longer cause a compiler
       internal error.

    o  The display of S-Float constants in listing files no longer
       causes an error.
