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).
