Differences from QB

• The QB ENVIRON statement is now called SetEnviron. The string type suffix "$" is required in the -lang qb dialect.
  The string type suffix "$" is optional in the -lang fblite dialect.
  The string type suffix "$" is ignored in the -lang fb dialect, warn only with the -w suffix compile option (or -w pedantic compile option).
