Entry of a symbolic complex number in polar form '(A,<B)' A,B,C,D returns 'B*COS(A)-i*B*SIN(A)' instead of 'A*COS(B)+i*A*SIN(B)' The NXEQ operation executed from the Graphics environment with A the Numerical Results flag (-3) set, may cause the current equation to be overwritten with a numerical value. The KGET command will cause calculator memory to be cleared if A you attempt to transfer a file of length 0 (zero) from your computer. If the Clock Format flag (-41) is set, so that the time is A displayed in 24-hour format, the Alarm Catalog will show the incorrect ones-digit for minutes in the alram time. The INV command returns an incorrect result if you attempt to A,B,C invert an 8 by 8 or larger matrix. And, there they are...the sheet includes workaround and avoidance procedures...but they're pretty stupid [like don't do it! kind of avoidance steps]. / internet: Chen@Gumby.UCalgary.CA ___ Lunatic Haven BBS / / [CA 403 239 1225] / __ __ __ __ __ / __ / /_/ / / /_/ /_ /\ / / /_ / /_/ /_ /\ / /___ / / /_/\/ / \ /__ / // /__ /__ \__/ / / /__ / // "I'm crazy, I don't work for anybody, and I'm having fun" BITNET: Chen%Mv2@UNCAEDU or Chen%Mv4@UNCAEDU - The Dreamer
