As a library programmer, I have done quite a few unreleased, it would be really nice to have a way of sending a special number to abort to indicate the type of error. Like the magic number previously suggested, but perhaps a different number for different types of number. Abort would become procedure abort( integer number ) if number < 0 then display crash message write to crash file abort with 256 + number*-1 end if abort with number end procedure each magic number would have a set standard meaning eg -1 other error -2 invalid subscript -3 not an atom -4 invalid routine id etc That way te interpreter/library would deal with the error properly displaying te correct message. ------------------------- Sincerely, Mathew Hounsell mat.hounsell at excite.com
