- OSErr … an MPW tool to find the meaning of Macintosh result codes.
-
- The problem is that Macintosh result codes are peppered through several
- thick volumes of information. This tool is an attempt to put them into
- one place. In addition, the tool can be modified to include result codes
- added to MacOS.

- WARRANTY/GUARANTEE:
-
- Be serious. If you break this application, you own both pieces.
-
- INSTALLING OSErr:
-
- Put the application "OSErr" into your MPW "Tools:" folder.
-
- USING OSErr:
-
- You must be running MPW.
- Type "OSErr" followed by the negative number returned by a MacOS function,
- then press ENTER or COMMAND-RETURN. If OSErr understands the number, it
- will display its meaning using StdOut. In most cases, you will also get
- some cross-reference information that tells you which Apple technical document
- you can look at for more information.
-
- MODIFYING OSErr Messages:
-
- This requires the application REZ, available from Apple.
-
- The error messages are contained in several 'STR#' resources. Each resource
- has room for 100 messages.
-
- To add a new message to an existing 'STR#' resource, just type the text.
-
- If you need to add a new 'STR#' resource, you will also have to add an entry
- in an Error Look Up Table resource (or 'eLUt'). The 'eLUt' is an array
- that includes the bottom number of a 'STR#' resource and the 'STR#' resource
- number. For example, if "STR# 4000" includes the text for errors -101 to -200,
- the 'eLUt' entery would be "101,4000".
-
- MODIFYING OSErr Source:
-
- Requires MPW C, V3.
