- This note tells how to use 4th Dimension with MultiFinder.

-
- Apple has announced MultiFinder, the first-generation multitasking operating environment for the
- Macintosh. Under MultiFinder, many applications may be open at once, with fast context switching
- and some background processing capabilities provided.
-
- Applications can work with MultFinder in two ways:
-
- 1. MutiFinder compatible. This means that the application functions correctly when running with
- MultiFinder. 4th Dimension is MultiFinder compatible.
-
- 2. MultiFinder aware. This means that the application can perform some functions in the
- background when MultiFinder is running. 4th Dimension is also MultiFinder aware.
-
- When using 4th Dimension with MultiFinder, your databases can search, sort, and run procedures
- in the background. To set up 4th Dimension for background operation, you have to do two things:
- set a bit with ResEdit, and set an option with 4D Customizer. Here's what you have to do:
-
- 1. Run ResEdit. Open 4th Dimension. Open the SIZE resource with ID 0. After the first two bits,
- the remaining bits are listed as "Undef bit" (undefined bit). The second undefined bit tells
- MultiFinder that the application can run in the background. Click the "1" radio button to turn this bit
- on. Close the SIZE 0, SIZEs, and 4th Dimension windows, and save the changes.
-
- 2. Run 4D Customizer. Open 4th Dimension. Click the two check boxes in the "Desk accessories"
- section in the upper right corner labeled "During thermometer" and "During printing." Close 4th
- Dimension and save the changes.
-
- The copy of 4th Dimension has now been set up to work in the background under MultiFinder.
- When you search, sort, or run a procedure, you should be able to switch to other applications.
-
- Remember that MultiFinder, as of this writing, is prerelease and still contains bugs, so you should
- be very careful as you use it with 4th Dimension or any other applications.
