+/* The pass 1 intermediate file has the following format:
+
+	<ascii-integer-rep> [ : [ <sp> [ <data> ]]] \n
+
+   e.g.   1: This is a comment
+
+   This format is destined to change in the future, but for now a readable
+   form is more desirable than a compact form.
+
+   NOTES ABOUT THE P1 FORMAT
+   ----------------------------------------------------------------------
+
+	P1_COMMENT:  The comment string (in   <data>)   may be at most
+		COMMENT_BUFFER_SIZE bytes long.  It must contain no newlines
+		or null characters.  A side effect of the way comments are
+		read in   lex.c   is that no '\377' chars may be in a
+		comment either.
+
+	P1_SET_LINE:  <data>  holds the line number in the current source file.
+
+	P1_INC_LINE:  Increment the source line number;   <data>   is empty.
+
+	P1_NAME_POINTER:  <data>   holds the integer representation of a
+			  pointer into a hash table entry.
+
+	P1_CONST:  the first field in   <data>   is a type tag (one of the
+		   TYxxxx   macros), the next field holds the constant
+		   value
+
+	P1_EXPR:  <data>   holds the opcode number of the expression,
+		  followed by the type of the expression (required for
+		  OPCONV).  Next is the value of   vleng.
+		  The type of operation represented by the
+		  opcode determines how many of the following data items
+		  are part of this expression.
+
+	P1_IDENT:  <data>   holds the type, then storage, then the
+		   char string identifier in the   addrp->user   field.
+
+	P1_EXTERN:  <data>   holds an offset into the external symbol
+		    table entry
+
+	P1_HEAD:  the first field in   <data>  is the procedure class, the
+		  second is the name of the procedure
+
+	P1_LIST:  the first field in   <data>   is the tag, the second the
+		  type of the list, the third the number of elements in
+		  the list
+
+	P1_LITERAL:  <data>   holds the   litnum   of a value in the
+		     literal pool.
+
+	P1_LABEL:  <data>   holds the statement number of the current
+		   line
+
+	P1_ASGOTO:  <data>   holds the hash table pointer of the variable
+
+	P1_GOTO:  <data>   holds the statement number to jump to
+
+	P1_IF:  <data>   is empty, the following expression is the IF
+	        condition.
+
+	P1_ELSE:  <data>   is empty.
+
+	P1_ELIF:  <data>   is empty, the following expression is the IF
+		  condition.
+
+	P1_ENDIF:  <data>   is empty.
+
+	P1_ENDELSE:  <data>   is empty.
+
+	P1_ADDR:   <data>   holds a direct copy of the structure.  The
+		  next expression is a copy of    vleng,   and the next a
+		  copy of    memoffset.
+
+	P1_SUBR_RET:  The next token is an expression for the return value.
+
+	P1_COMP_GOTO:  The next token is an integer expression, the
+		       following one a list of labels.
+
+	P1_FOR:  The next three expressions are the Init, Test, and
+	         Increment expressions of a C FOR loop.
+
+	P1_ENDFOR:  Marks the end of the body of a FOR loop
