Can anyone help me with this one? I am trying to take all the stuff that's in the Data fork of a file and change it into a CODE type and put it into the resource fork of the file. The program that I'm trying to disassemble with MacNosy uses a short program to read the Data file (it's actually code though) into RAM and then sets up all the pointers and jumps to it. I've tried using TMON to just trace through the code when it's in RAM, but the program re-assigns alot of the system pointers etc. and I can only trace so far with TMON before the whole thing just blows up. MacNosy will only lets you disassemble all the stuff (like CODE types) in the resource fork of APPL files. So what i really need to do is convert the data fork to a resource fork of type CODE. Any help would be appreciated. Peter Espen (espen@well)

For example: Read 'CODE' (1) "TheFileName"; This statement would save the contents of TheFileName's data fork as a CODE resource with an ID of 1. Tom Taylor Development Systems Group

Then you tell Nosy to disassemble the file, it will see that you have loaded it into switcher and you can play with it from there. The latest version of Nosy is 2.25 (or even higher now), which has this capability, plus the ability to use the new debugger. Get onto the Nosy SIG on Delphi and they explain more on how to do this. I hope this info helps. If not, you can always leave mail for MacNosy of Delphi and Jasik will answer your questions fairly promptly. Note: Standard disclaimer, I have no connection with Steve Jasik, aka MacNosy, aka The Head Nose, etc... I am just an impressed customer who can't wait to have enough time to sit down and play with the sucker (MacNosy). -- Brian Bezanson {seismo,ihnp4,allegra,topaz,harvard}!uwvax!gumby!bezanson Manta Software Corp. bezanson@gumby.wisc.edu

You would take the output of the data fork in hex and then shove
it into a resource compiler.
Using RMaker, you would use the type GNRL followed by a .H, as described
in the appropriate documentation. Using the MPW compiler Rez, you would
define a CODE as a type with just an integer array.
