High Quality Content by WIKIPEDIA articles! S-Lang is an interpreted programming language designed by John E. Davis to provide extensibility to C-based applications in the form of an embedded interpreter. Created in 1992, its original syntax reflected its origins as a stack-oriented language, but the current syntax has evolved to more closely resemble that of C. S-Lang is small, simple, and dynamically typed, with strong support for numerical array-based operations. Because of its size and ease-of-embedding, S-Lang has been embedded in non-numerical programs such as the slrn newsreader and the JED text editor.
