+Dear Dr. Ishikawa:
+.bl 1
+.fill
+Thank you for your letter on CP/M-68K.  We certainly appreciate your effort
+in helping us make CP/M-68K a better product.  Here are our answers to the
+issues you raised.
+.bl 1
+Bugs:
+.bl 1
+.ls
+.la;Changing file attributes with STAT does cause the first letter of the
+extension to disappear.  This is due to the CCP not ANDing off the high-order
+bit of the character before outputting it to the screen.  This bug is fixed
+in the 10/8 release.
+.la;Non-zero user areas do not work in the 7/31 version of the system. This
+bug is also fixed in the 10/8 release.
+.la;Source files which do not have single-character extensions cannot be
+assembled.  This is a restriction imposed by the assembler.
+.la;The "-s" option of lo68 with which you had trouble seems to work on
+our copy of the system.  The relocation bits are unaffected by this flag.
+.la;The "-x" option of lo68 is used to retain LOCAL symbols of the assemblies 
+or compiles which make up the input to the linker.  Symbols beginning with
+"L" are suppressed by this flag.  The C compiler uses symbols beginning with
+"L" for compiler-generated temporary labels.  The "-x" option removes these.
+.la;Relocatable command files may be generated by using the "-r" option of
+LO68.  The default is to generate absolute command files.
+.la;The disk change bug which you reported has been corrected in the 10/8 
+release.  The problem stemmed from the fact that the OLD diskette directory
+was retained in memory by the BIOS.  
+.la;Relocation bits for the data segment are not produced unless the "-r"
+option is specified.

+Assembler Requirements:
+.bl 1
+.ls
+.la;We have been promised an update to the assembler to make it compatible
+with Motorola syntax.  We will place this either on the present release
+or on the next release of CP/M-68K, depending on when we receive the 
+update from Alcyon.
+.la;Source file concatenation with the assembler may be accomplished using
+the C preprocessor (CP68) supplied with the 10/8 release.
+.els
+Questions:
+.bl 1
+.ls
+.la;Floppy disk initialization will be performed via a FORMAT utility which
+uses the UDC (Univeral Device Controller) FORMAT feature.
+.la;The bootstrap utility will be supported much the same as in CP/M-86:
+A loader program will reside on the first two tracks of the disk.  This 
+loader will be brought into memory by the BOOT ROM, and will load the file
+CPM.SYS from drive A:.  Detailed specifications will be delivered with the
+10/8 release.
+.la;We do not plan on generating CP/M diskettes under Versados.  The 
+S-records for the system will be supplied on Versados diskettes, and
+CP/M can be built with MBLM.  The EXORmacs emulator and other debugging
+tools can be used for debugging CP/M built from these S-records.
+.la;We do not plan to have a file conversion utility from CP/M to Versados.
+.els
+Again, thank you for your efforts in helping us debug CP/M-68K.
+If any other bugs or questions should arise, please do not hesitate to 
+contact us.
