+Software and language are **intrinsically** related, since software may process language, and is constructed in language.
+Yet *language* means different things in the context of ~computing~: formal languages in which algorithms are expressed and software is implemented, and in so-called “natural” spoken languages.
 There are at least two layers of formal language in software: programming language in which the software is written, and the language implemented within the software as its symbolic controls.
 In the case of compilers, shells, and macro languages, for example, these layers can overlap.
 “Natural” language is what can be processed as data by software; since this processing is formal, however, it is restricted to syntactical operations.

 But these languages can also be used outside machines—in programming handbooks, for example, in programmer’s dinner table jokes, or as abstract formal languages for expressing logical constructs, such as in Hugh Kenner’s use of the Pascal programming language to explain aspects of the structure of Samuel Beckett’s writing.1 In this sense, computer control languages could be more broadly defined as syntactical languages as opposed to semantic languages.
 But this terminology is not without its problems either.
 Common languages like English are both formal and semantic; although their scope extends beyond the formal, anything that can be expressed in a computer control language can also be expressed in common language.

 It follows that computer control languages are a formal (and as such rather primitive) subset of common human languages.
 To complicate things even further, computer science has its own understanding of “operational semantics” in programming languages, for example in the construction of a programming language interpreter or compiler.
 Just as this interpreter doesn’t perform “interpretations” in a hermeneutic sense of semantic text explication, the computer science notion of “semantics” defies linguistic and common sense understanding of the word, since compiler construction is purely syntactical, and programming languages denote nothing but syntactical manipulations of symbols.

 10. Alan Kay, an inventor of the graphical user interface, conceded in 1990 that “it would not be surprising if the visual system were less able in this area than the mechanism that solve noun phrases for natural language. Although it is not fair to say that ‘iconic languages can’t work’ just because no one has been able to design a good one, it is likely that the above explanation is close to truth.” This status quo hasn’t changed since.
