is "of" a cas operator?
I was doing some experiments to see what XCas functions were implemented (or not) in the HP Prime's CAS implementation. I tried the user_operator command as in:
user_operator("R",(x,y)>(x*y+x+y),Binary) (works in XCas). I got an error message: of(['Error: Bad Argument value']) My question is that even though I'm sure user_operator isn't implemented in the Prime, which part of what I typed was getting the Bad Argument? Is "of" referring to an operator or something? Thx Donald

User function applied to something, like f(x), are internally represented by a tree with rootnode of and 2 arguments f and x : of is a commandname
