+# BBCZ80
+BBC BASIC (Z80) v5 is an implementation of the BBC BASIC programming language for the Z80 CPU.
+It is largely compatible with Acorn's ARM BASIC V but with a few language extensions based on
+features of 'BBC BASIC for Windows' and 'BBC BASIC for SDL 2.0'. These extensions include the
+EXIT statement, the address-of operator (^) and byte (8-bit) variables and arrays (& suffix).
+
+More details of the features added in version 5.00 can be found in the file WHATSNEW.TXT.

+
+The files in green constitute the generic BBC BASIC interpreter which is shared by all the
+editions, it (just!) fits in 16 Kbytes so could be held in a ROM of this size.  The files in
+the blue box are used to build the CP/M edition.  The files in the red box are used to build
+the Acorn Z80 Second Processor edition (in principle: the source files are on an 8" floppy!)
+
+Note that the name 'BBC BASIC' is used by permission of the British Broadcasting Corporation
+and is not transferrable to a derived or forked work.
