(see desc in Chapter 9) in desc[x;y], x is an atomicsymbol instead of the required list of A's and D1s,UNEQUAL LENGTH LISTS -MAP2-This error can occur only during the differentiation func-tion; it implies a machine error,1ST ARG.LIST TOO SHORT -PAIR-AM. LIST TOO SHORT PAIR-F2 'and F3 occur when a list of pairs is being created outof two lists, for example when a list of dummy variablesand their values is being appended to the p-list,Theitems still remaining on the larger list are printed outfollowing the error indication.' F4 CANNOT PAIR OBJECTS. PLEASE USE LIST -PAIR-1.e. one of the lists to be paired is, erroneously, an(~5LF~atomic symbol.This usually happens when the user gives asingle dummy variable in a LAMBDA expression as an atomicsymbol instead of as a list. The list is printed out fol-lowing the error indication,FLVAL ASKED TO FIND VALUE OF NON-OBJECTFLVAL ASKED TO FIND VALUE OF NON-FLOATING POINT NUMBERF5 and F6 occur when the program is looking for the valueof a floating-point number,and finds either that it is notan atomic symbol (~5), or that it is not a floating-pointnumber ( ~ 6 ) ~
