Subject: SPC700 additions.
* First completed version of SPC700. Very untested.
* Fixed an oddity in the parser regarding quoted values not ending with a
separator. These values now appear unquoted with the additional text included
in the same argument.

+SPC700 CPU
+
+Using the SPC700
+
+The SPC700 processor can be selected by passing spc700 to the processor
+directive, i.e.
+
+
+ processor spc700
+
+
+Opcodes
+
+I could find no official documentation on The SPC700, so the assembler uses what
+seems to be the accepted opcode format.
+
+
+Options
+
+The SPC700 assembler has the following options.
+
+
+
+SPC700 Option |
+Description |
+
+
+option direct-page, <on|off|auto>
+ |
+
+Controls the assumptions made regarding Direct Page address. Defaults to
+auto, and can be the following values:
+
+
+
+off
+ |
+
+All addresses are assumed to be not on the Direct Page, regardless of the value
+used.
+ |
+
+
+on
+ |
+
+Assumes all addresses are in the Direct Page, raising an error if any address is
+not in the Direct Page.
+ |
+
+
+auto
+ |
+
+Treats addresses less than 256 as being in the Direct Page automatically. This
+mode also makes the assembler perform an extra pass to guard against the
+possibility of the calculation being fooled.
