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).
