COBCH1716 Best visible instance overload found in <type-name> is <method-name> which has invalid parameter <param-num>

In the following example, there is no compatible match for the call to messageStart using the arguments supplied. There is a method with the correct name and same number of parameters; however, the parameter is not a compatible match. Either change the argument to be compatible with a string type, or change the messageStart method to accept a type compatible with a numeric.

class-id myClass2.
method-id main.
 declare messDisplay as type myClass2
 invoke messDisplay::messageStart(2)
end method.
method-id messageStart.
procedure division using by value s as string.
...
end method.
end class.

This error is produced in a context in which an instance method would be allowed.
