You don't really give enough information for us to give definite help.
We have no idea what the subtype of Bs is, nor what context clauses
you have.

GNAT is trying to find a function "*" that takes universal_integer (or
a type that it can be implicitly converted to) for its 1st operand,
and a string type for its right operand. Apparently no such function
is visible, and it's telling you what is needed to match a visible
function "*" that it did find. Clearly that msg isn't useful for you.

There are such functions defined in the various Ada.Strings.* pkgs.
Perhaps you have mentioned one of those in a context clause, but have
not made the function directly visible through a renaming, a use
clause, or a use type clause. You could either add such direct
visibility, or use the function's full name:

Bs :=3D Ada.Strings.Fixed."*" (20, " ");

for example.
