PATCHING THE DEFAULT DRIVES

Unfortunately, the author of YAYANC presumed that all systems it
would be running on would be twin floppy systems, with the MAST.CAT
always on A: and the disk to be catalogued always on B:.  

No big deal to change it as he did include his source code.  However,
it requires the BDS-C Compiler, which not everybody, including me, has.

So, I went poking around at the hex level and found the bytes that
control the default drives.  So, if you want to alter the drives
permanently so as not to be bothered with this otherwise compulsory
menu selection before you can get going, get out your favorite byte
basher, such as PATCH, ZAP, EDFILE, etc., and make the following
changes:

   Byte 08DEh - Default drive for MAST.CAT 
                (currently 41h = A drive)
   Byte 08E3h - Default drive for disk to be cataloged.  	
                (currently 42h = B drive) 

Because I have a hard disk system where my single floppy is always
the C: drive, I changed these bytes as follows:

   Byte 08DEh - changed to 42h (B) as my MAST.CAT is on B
   Byte 08E3h - changed to 43h (C) as C is always the drive I
                use for the disc to be cataloged.
