+
+
+
+        These release notes pertain to both the software  and
+        the   documentation  set  for  the  Digital  Research
+        product:
+
+
+                       Programmer's Utilities
+
+                    For the IBM Personal Computer
+                        Disk Operating System
+
+
+
+        They provide the most current information regarding:
+
+           o changes and corrections  to  the  software  that
+             have  been  identified  since  the  product  was
+             released.
+
+           o errors or omissions  in  the  documentation  set
+             that  could not be corrected because of the lead
+             time needed for production and printing.
+
+
+
+        Note:  These release notes have been formatted so you
+        can  print them on your own printer, cut them to size
+        (6 1/2 x 8 1/2), and place them in your manuals.

+
+                            LINK-86 Notes
+
+
+        A new command line  option  has  been  added  to  the
+        linker.  The  $MY  option directs LINK-86 to send the
+        .MAP file to your line printer.
+
+        A new optional parameter has been added  to  the  MAP
+        option. The  NOCOMMON  parameter  directs  LINK-86 to
+        suppress the listing of common segment names  in  the
+        MAP file.
+
+        LINK-86 now displays the  filename  and  module  name
+        indicating the location of an undefined symbol.
+
+        LINK-86  can  now  report  three   additional   error
+        messages:
+
+          CLASS NOT FOUND  -  The class name specified in
+          the command line does not exist in any of the
+          files being linked.
+
+          GROUP NOT FOUND  -  The group name specified in
+          the command line does not exist in any of the
+          files being linked.
+
+          SEGMENT NOT FOUND  -  The segment name specified
+          in the command line does not exist in any of the
+          files being linked.

+
+                           RASM-86 NOTES 
+
+
+        A new command line option has been added to the RASM-
+        86  assembler.  The $NC option directs RASM-86 not to
+        convert letters in symbol names to  uppercase.   This
+        feature supports users of the C language.
+
+        RASM-86  Version  1.3  now  supports  8087   opcodes.
+        However,  RASM-86  does  not  allow  types other than
+        byte, word, and double-word.  Therefore, in order  to
+        support  the 8087 instructions, the form of the RASM-
+        86 instruction is slightly different from  the  Intel
+        convention.
+
+        All memory reference instructions have two characters
+        appended  to  the  end  of  the opcode name.  The two
+        characters represent the number of bits referenced by
+        the instruction.  For example,
+
+             FADD64   byte ptr  my_var
+
+
+        This instruction assumes that my_var contains 64 bits
+        (4  bytes).  This  convention  applies  to  all  8087
+        instructions that reference user memory, except those
+        that  always  reference the same number of bits (i.e.
+        FSTCW).
+
+        Also, in the Intel convention, any  instruction  that
+        is followed by a P causes the stack to be popped.  In
+        RASM-86, the P  follows  the  number  of  bits.   For
+        example,
+
+             FSUB80P   byte ptr  my_var; sub and pop temp real
+
+
+        We recommend that you carefully study all  the  Intel
+        documentation  about  the  8087  coprocessor  and its
+        opcodes before using them in RASM-86.
