The seven possible errors are coded in the four bit FEC (Floating Exception Code) register as follows: 2 Floating Op code error 4 Floating divide by zero 6 Floating (or double) to integer conversion error 8 Floating overflow 12 Floating undefined variable 14 Maintenance trap You can find this value by running PFE (I). Also, using ADB on your core dump might prove helpful. Perhaps UNIX-WIZARDS is not the right place to send questions like this? -Mike ----------------------------------------------------------------- gopher://quux.org/ conversion by John Goerzen of http://communication.ucsd.edu/A-News/ This Usenet Oldnews Archive article may be copied and distributed freely, provided: 1.
