Methods with Parameters

All methods in X++ have their own scope. To use data from a different scope,
transfer the data into the new scope using parameters.
A method can have one or more parameters. Within the scope of the method
these parameters are treated like local variables, initialized with the value from
the parameter in the method-call.

private void methodWithParameters(str parm1,int _parm2 = 1) { }

All parameters are passed by value, this means you cannot change the value of
the original variable, but only the local variable in the method, which is a copy of
the original.
In the previous example, the second parameter is assigned a default value. This
means that when the method is called, the second parameter is optional. If it is
called without a second parameter, _parm2 will be set to 1.
