Bug with CONCAT

Try CONCAT(5,6) returns 0. ???

CONCAT(5,6,7) returns [ 5 6 7 ], as it should.

In a program, for now, one can get around this problem with defining a list first, e.g.,

l:= {}

l:=CONCAT(l,5);

l:=CONCAT(l,6);

RETURN (l); returns the list {5, 6}.

I thought I should mention this because I got unexpected results in my program, and was finally able to trace it - - I called RETURN(CONCAT(v1,v2)) and obtained 0.

Also CAS programs really should be debuggable (just like PPL programs) - - why is the DEBUG soft key missing for CAS programs in the editor?

I think if you try the function \( cat \) you will get the response you are looking for?

The user manual only states CONCAT to be used with lists so you may be confusing the parser?
