- Sub: qNeedsROM128K & PrintTraps
-
- If I compile an application with qNeedsROM128K set true and then run it on a
- 512e (a 512e has 128K ROMs, right?) with System 3.2 (the officially recommended
- system for a 512e), the application bombs with an ID = 12. If I run it with
- System 3.4, it runs properly.
-
- This problem seems to be caused by the unit UPrinting.p which assumes that the
- print traps are present if qNeedsROM128K is true. (I am using 2.0b9 with
- Think, but 2.0 final also makes this assumption.) According to IM-V the print
- traps were implemented in System 4.1. Why are the print traps present on my
- 512e with System 3.4? Are the print traps in System 3.4 or are they in the
- newer ImageWriter file? What is the minimum system configuration on which a
- MacApp application with qNeedsROM128K set true will run?
-
- I see no problem with UPrinting requiring the print traps on a 128K machine,
- but it could be a little more polite and check for the presence of the print
- traps. If the traps aren't present, MacApp could inform the user (in a
- appropriately apologetic tone) that the application can't be run with their
- antiquated System.
