I have successfully patched MacApp 1.1.1 to allow creation of a debugging
version with MPW 3.0.  We use the debugging version daily here on the
MacGnome project, and it seems to work fine.  It's been a while, but here is
a list of what I think I did to get it to work:

UMeasure.p, Line 10:
	 Changed the {$D++} to {$D+}

UTrace.inc1.p, Lines 994-996:
	Replaced this While loop with the While loop and adjacent If
	statement from the MacApp 2.0 code:
		{Search for RTS or JMP (A0) or RTD #$00nn}	
		{Thanks to Mike Bentley}
		WHILE (pc^ - 1 <> $4E75 - 1) &
		  (pc^ - 1 <> $4ED0 - 1) &
		  (pc^ - 1 <> $4E74 - 1) DO
			pc := ZPINTEGER(ORD(pc) + 2);

		IF pc^ - 1 = $4E74 - 1 THEN
			{If it was RTD, skip past displacement}
			pc := ZPINTEGER(ORD4(pc) + 2);
MacApp.make1, Line 10:
	Add the compiler switch "-mbg ch8" to the PascalOptions variable.
