If you want to call it from Spad you need to use something like: (getDependentsOfConstructor$Lisp)((INTERN$Lisp)("Integer")) or maybe use FIND_-SYMBOL insted of INTERN. I do not know if there is easier method to pass Lisp symbol from Spad to Lisp function.
Excellent! Depending on what you know about an object you might also prefer to use devaluate to get the symbol for example: (1) -> parentsOf(CAR(devaluate(Integer)$Lisp)$Lisp)$Lisp (1) (((IntegerNumberSystem) . T) ((ConvertibleTo (String)) . T) ((OpenMath) . T)) Type: SExpression Note that on Axiom for Windows 0.1.4 I get the following error: (2) -> )lisp (|getDependentsOfConstructor| '|Integer|) >> System error: Caught fatal error [memory may be damaged] but I think that may be corrected in wh-sandbox compiled for Windows. I will test that later. Regards, Bill Page.
