[Maxima-discuss] Assigning a setting-predicate in a .mac file

[Gunter K. <gu...@pe...>]

Dear all,

Is there a way to tell a .mac file to limit a variable to be assigned 
only integers to - or to ensure it passes any other test one can write 
in the maxima language before actually changing its value?

Thanks a lot,

and kind regards,

    Gunter.
