Managing Information Aggregates in the KR Framework

• The operator addent is undefined (mentioned in Section 3.2)
• The attribute read-in-file is only partially available
• The operator Cur shall be given with one argument. The argument is not in use, however.

List Processing in the KR Framework

• The function en gives the wrong results
• For definitions using def see above. (Compare Section 2.7).
• The function type-of gives the wrong value
• The predicate gt and its negation -gt cause an error in execution. However gt= executes correctly.
• Note that the function sort with str.prec as its second argument will only work correctly for a sequence where all elements are strings, and not if there are e.g. symbols or numbers in the sequence.

Miscellaneous

According to the command-line conventions, if a command line starts with a full stop (i.e. a point) then the rest of the line will be assumed to be an S-expression and it will be given to the CommonLisp interpreter. This is inconvenient if one really wishes to obtain the value of a Leonardo session variable since it is by convenion preceded by a full stop as well. In this case one may use the command show like in the following example.

ses.263) ssv .a {b c d}

ses.264) show .a
{b c d}
