How to use this tool?

This free online converter lets you convert code from Fortran to Lisp in a click of a button. To use this converter, take the following steps -

  1. Type or paste your Fortran code in the input box.
  2. Click the convert button.
  3. The resulting Lisp code from the conversion will be displayed in the output box.

Examples

The following are examples of code conversion from Fortran to Lisp using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.

Example 1 - Is String Palindrome

Program that checks if a string is a palindrome or not.

Fortran

Key differences between Fortran and Lisp

CharacteristicFortranLisp
SyntaxFortran uses a fixed-format syntax, which can be difficult to read and write. It also has limited support for modern programming constructs such as object-oriented programming.Lisp uses a prefix notation syntax, which can be unfamiliar to programmers used to infix notation. However, it is highly flexible and allows for the creation of powerful macros.
ParadigmFortran is primarily a procedural programming language, although it does support some object-oriented programming constructs.Lisp is a functional programming language, although it also supports imperative and object-oriented programming.
TypingFortran is a statically typed language, which can help catch errors at compile time. However, it can also make the language more verbose.Lisp is dynamically typed, which can make it more concise and flexible. However, it can also make it more prone to runtime errors.
PerformanceFortran is known for its excellent performance, particularly in scientific and engineering applications.Lisp is generally not as performant as Fortran, although it can still be used for some high-performance applications.
Libraries and frameworksFortran has a number of libraries and frameworks available for scientific and engineering applications, although it may not have as many options as some other languages.Lisp has a smaller ecosystem of libraries and frameworks compared to some other languages, although it does have some powerful tools for artificial intelligence and natural language processing.
Community and supportFortran has a dedicated community of users, particularly in the scientific and engineering fields. It also has good support from vendors such as Intel and IBM.Lisp has a smaller community compared to some other languages, although it does have some dedicated users and open-source projects.
Learning curveFortran has a relatively low learning curve for programmers with experience in other procedural languages. However, its fixed-format syntax can be challenging for some beginners.Lisp has a steeper learning curve compared to some other languages, particularly for programmers who are not familiar with functional programming concepts.
