There's a TLA that rings a bell. "Permanent Temporary Fix"? Or was that a reinterpretation? But yes, it's clearly source-related. > reassemble the modules, relink into a kernel/system image/whatever > the os-appropriate nomenclature is. Yup. That reminds me of a poem published in Datamation decades ago: On either die the printer lie Fat stacks of paper six feet high That stun the mind abnd blur the eye, And lo! Still more comes streaming by, A fresh SYSABEND dump. Ye printer clackth merrily "Compleccioun code is 043" Alack! What can the matter be That made SYSABEND dump? My TCAM hath no MCP? My data cannot OPENed be? Consult my neighbourhood SE? The devil take thy dam and thee, Thou vile SYSABEND dump! Assemble modules on the fly And link for yet another try. With SUPERZAP a patch apply, This time THOU SHALT NOT DUMP! On either side the printer lie Fat stacks of paper twelve feet high That blow the mind and blast the eye. Gadzooks! How shrill yon varlet's cry As sixteen megabytes go by In yet another dump. Greg -- Sent from my desktop computer. Finger grog at lemis.com for PGP public key.
