I have a script which calls the following functions
   ⊤
   &middle;
   &end;
In a script to be required, I have the following definitions: (notice top is not defined)
   sub middle {}
   sub end {}
Is there a way to wrap the call to function top() with an if statement of some sort so it will not get a function undefined error?
Something like:
If top function exists {
   ⊤
}
