The ObiWan Force Database should be placed in the ObiWan Folder in the Preferences Folder in the System Folder. If you don’t have ObiWan, you can get it from all the usual archives (info-mac/cp (its currently in info-mac/app, but it should move to its proper location in the cp directory shortly)), or you can get it from redback.cs.uwa.edu.au in /others/peterlewis.
The Force file includes all the System 7 information contained in the PInterfacesHelp file from Apple (thanks go to Apple for licensing this file to me for free!), together with a bunch of additions, including
IM 1 to 6 procedures (eg InitGraf)
IM 1 to 6 types (eg FSSPec)
IM 1 to 6 traps (eg _InitGraf and TrapA86E)
IM 1 to 6 globals (eg CurApName and Global910)
IM 1 to 6 errors (eg dsMemFullErr, Err25, nilHandleErr, Err-109)
plus additions (mostly all done by Quinn)
Ascii - an ascii chart
Filter Procs - most of the important filter procs from IM
FinderFlags - the finder flags
Help - a description of the keys for ObiWan (type cmd-`,a,<return> to dispay the help)
