It also compiles on Sun's fussy compiler when IEEE flags are included.

I was given a program that compiles on Compaq Fortran. I'm not much of a fortran programmer so I'm throwing myself on the mercy of the forum. Both provide the same capabilities, so we'll describe the pros and cons of each for different cases and provide recommendations on their use.Greetings. Each scope function uses one of two ways to access the context object: as a lambda receiver ( this) or as a lambda argument ( it). Inside the lambda of a scope function, the context object is available by a short reference instead of its actual name. There are two main differences between each scope function: Distinctionsīecause the scope functions are all quite similar in nature, it's important to understand the differences between them. Avoid nesting scope functions and be careful when chaining them: it's easy to get confused about the current context object and the value of this or it. The use cases of different functions overlap, so that you can choose the functions based on the specific conventions used in your project or team.Īlthough the scope functions are a way of making the code more concise, avoid overusing them: it can decrease your code readability and lead to errors. Grouping function calls on an object: with Running statements where an expression is required: non-extension run

Object configuration and computing the result: run Introducing an expression as a variable in local scope: let Here is a short guide for choosing scope functions depending on the intended purpose:Įxecuting a lambda on non-null objects: let The detailed information about the differences is provided in the dedicated sections below. No: takes the context object as an argument.
