ML exception types. To define an exception type in ML, we use an exception declaration, which has the form: exception constructorName of arguments. The of arguments clause is optional. Note the similarity to a case in a datatype declaration. In fact, technically, what this declaration does is add an additional case to the built-in exn type:, Standard ML exceptions. – exception Negative of string > exn Negative = fn : string -> exn – local fun fact 0 =1 | fact n = n* fact (n-1) in fun factorial n= if n >= 0 then fact n else raise Negative Insert a positive number!!! handle Negative msg => 0 end, The base class for all Azure Machine Learning exceptions. This class extends the Python Exception class. If you are trying to catch only Azure ML exceptions, then catch them with this class.
This chapter is concerned with exceptions the other forms of effects will be dealt with later in these notes. A basic use of exceptions in ML is to signal error conditions. ML is a safe language in the sense that its execution behavior may be understood entirely in terms of the constructs of the language itself.

Standard ML is a general-purpose, modular, functional programming language with compile-time type checking and type inference. It is popular among compiler writers and programming language researchers, as well as in the development of theorem provers. SML is a modern dialect of ML, the programming language used in the Logic for Computable Functions theorem-proving project. It is.
Source Level Debugging in Poly/ML . Poly/ML includes a source-level debugger. You can use it to set breakpoints in the program and print the values of local variables.
