+			 * This is a recursive descent parser for

+			 * It tries to recognize EM code that loads exactly
+			 * 'nbytes' bytes on the stack.
+			 * 'l' is the last instruction of this code.
+			 * On toplevel, when an expression has been
+			 * recognized, the procedure-parameter

+			 * last instruction of the expression and the number of
+			 * bytes recognized.
