This program should verify that the 68881 is installed and create a 'resource' and add it to the system list of resources. The 1.3 ieee libraries look for this resource when they are initialized. If it is not found it uses software emulation to provide the floating point functions. = = =Dave Chuchem =chuchem@bguee.bitnet -- Dale Luck GfxBase/Boing, Inc. {uunet!cbmvax|pyramid}!amiga!boing!dale
