+/*===========================================================================
+  We assume that instructions are unsigned numbers.
+  All instructions have an opcode in the first 6 bits.
+  Instructions can have the following fields:
+	'A' : 8 bits
+	'B' : 9 bits
+	'C' : 9 bits
+	'Ax' : 26 bits ('A', 'B', and 'C' together)
+	'Bx' : 18 bits ('B' and 'C' together)
+	'sBx' : signed Bx
+
+  A signed argument is represented in excess K; that is, the number
+  value is the unsigned value minus K. K is exactly the maximum value
+  for that argument (so that -max is represented by 0, and +max is
+  represented by 2*max), which is half the maximum for the corresponding
+  unsigned argument.
