Context_1 : WSFN (790 AM) is a sports radio station in Brunswick, Georgia. WSFN programming is simulcast on WFNS 1350 AM and W279BC 103.7 FM. Southern Media Interactive LLC, who also owns WSEG of Savannah ESPN Savannah/Hilton Head WSEG AM and WFNS of Blackshear. Context_2 : Dr. Dobb's Journal (DDJ) was a monthly journal published in the United States by United Business Media. It covered topics aimed at computer programmers. When launched in 1975, DDJ was the first regular periodical focused on microcomputer software, rather than hardware. In its last years of publication, it was distributed as a PDF monthly, although the principal delivery of "Dr. Dobb's" content was through the magazine's website. Publication ceased at the end of 2014, with the archived website continuing to be available online. Context_3 : A source-to-source compiler, transcompiler or transpiler is a type of compiler that takes the source code of a program written in one programming language as its input and produces the equivalent source code in another programming language. A source-to-source compiler translates between programming languages that operate at approximately the same level of abstraction, while a traditional compiler translates from a higher level programming language to a lower level programming language. For example, a source-to-source compiler may perform a translation of a program from Pascal to C. An automatic parallelizing compiler will frequently take in a high level language program as an input and then transform the code and annotate it with parallel code annotations (e.g., OpenMP) or language constructs (e.g. Fortran's codice_1 statements). Context_4 : WSFN ("Which Stands for Nothing") was a programming language for controlling robots created by Li-Chen Wang and published by Dr. Dobb's Journal in September 1977. It was later translated into Japanese and published by "ASCII". Context_5 : The PL/P programming language (an acronym of "Programming Language for Prime (computers)") is a mid-level programming language developed by Prime Computer to serve as their second primary system programming language after Fortran IV. PL/P was a subset of PL/I. Context_6 : Microsoft Visual Programming Language, or MVPL, is a visual programming and dataflow programming language developed by Microsoft for the Microsoft Robotics Studio. The Microsoft Visual Programming Language is distinguished from other Microsoft programming languages such as Visual Basic and C#, as it is the only Microsoft language that is a true visual programming language. Microsoft has utilized the term "Visual" in its previous programming products to reflect that a large degree of development in these languages can be performed by "dragging and dropping" in a traditional wysiwyg fashion. Context_7 : A toy language is a computer programming language that lacks the requirements to create reliable, maintainable computer programs in a production environment. Categorizing a programming language as a toy language is difficult, however, as the definition is often subjective. Also, a "toy" language is distinguished from domain-specific languages and esoteric programming languages. A "problem domain" language is a limited programming language made for a specific purpose, such as the PostScript language used in PDF documents, or the limited instruction set used to program the multiple core graphics processing unit in a video card. An "esoteric language" is a programming language designed to test the boundaries of computer programming language design, as a proof of concept, as software art, or as a joke, such as Befunge or LOLCODE. Context_8 : BCPL ("Basic Combined Programming Language"; or 'Before C Programming Language' (common humorous backronym) ) is a procedural, imperative, and structured computer programming language. Originally intended for writing compilers for other languages, BCPL is no longer in common use. However, its influence is still felt because a stripped down and syntactically changed version of BCPL, called B, was the language on which the C programming language was based. BCPL introduced several features of modern programming languages, including curley braces notation for code blocks; compilation via virtual machine byte code; and the world's first 'hello world' demonstrator program. Context_9 : An esoteric programming language (sometimes shortened to esolang) is a programming language designed to test the boundaries of computer programming language design, as a proof of concept, as software art, as a hacking interface to another language (particularly functional programming or procedural programming languages), or as a joke. The use of "esoteric" distinguishes these languages from programming languages that working developers use to write software. Usually, an esolang's creators do not intend the language to be used for mainstream programming, although some esoteric features, such as visuospatial syntax, have inspired practical applications in the arts. Such languages are often popular among hackers and hobbyists. Context_10 : In computing, a programming language specification (or standard or definition) is a documentation artifact that defines a programming language so that users and implementors can agree on what programs in that language mean. Specifications are typically detailed and formal, and primarily used by implementors, with users referring to them in case of ambiguity; the C++ specification is frequently cited by users, for instance, due to the complexity. Related documentation includes a programming language reference, which is intended expressly for users, and a programming language rationale, which explains why the specification is written as it is; these are typically more informal than a specification. fact_1 : WSFN ("Which Stands for Nothing") was a programming language for controlling robots created by Li-Chen Wang and published by Dr. Dobb's Journal in September 1977. fact_2 :  When launched in 1975, DDJ was the first regular periodical focused on microcomputer software, rather than hardware. Answer: 1975
Output: The WSFN programming language was published in a journal that was launched in what year?
