Re: [Axiom-developer] print or output in packages.

[Vanuxem Grégory]

Hi,

I use

 print("I am here")$Lisp
and 
 num := numer arg
 print (num::OutputForm)
 den := denom arg
 print (den::OutputForm)


For the error 1 is a function and it's difficult (i  don't know how)
to coerce it (I have previously spoken of this with Bill Page and I
don't really understand why).



Cheers,

Greg
