+Registers are referred to by their number, e.g., @code{9} means the
+integer register 9 or the FP register 9 (depending on the
+instruction).
+
+Because there is no way to distinguish registers from immediate values,
+you have to explicitly use the immediate forms of instructions, i.e.,
+@code{addi,}, not just @code{add,} (@command{as} does this
+implicitly).
+
+The assembler and disassembler usually supports the most general form
+of an instruction, but usually not the shorter forms (especially for
+branches).

 The Gforth project was started in mid-1992 by Bernd Paysan and Anton
