What's New:

- Somewhat under protest, I've allowed the SETPATH SBRLNK opcode to work at >17. This must be enabled per FIAD drive and is not supported on any other type.
- I found a misconfiguration of the save function for FIAD disk options - I recommend reviewing your disk settings for all 10 drives.
- The subdirectory API is still untested and all operations are limited to 10 characters except SETPATH, which is 39 as per MYARC. Unfortunately these are fixed length buffers and can't be safely extended.
