Plus Programming is an S-expression programming language from the University of British Columbia (Canada), based on the UNIX S-expression system language developed in the University of Toronto, ca. 1971. In addition, it contains the C and Fortran-specific extensions to allow it to compile into Fortran and C++ code, as well as for the C language. This is similar to other S-expression languages like Scheme, Prolog and Pcre. In fact, Plus Programming uses many of its features and is often used in conjunction with these S-expression languages.

The concept of S-expression was originally introduced by Donald Knuth at Stanford University and later extended by Richard Saul Wurman. The idea was that if you had a finite sequence of symbols, like a computer program, then you could define a syntax using a programming language. For example, if you wanted to define the syntax for a language which deals with a list of numbers, you could write down the list using the C programming language, which would evaluate to a finite sequence of symbols. If you wanted to define the syntax for a language that dealt with the stock market, you could write down a finite sequence of symbols in the stock market language. And so forth.

Plus Programming differs from other languages in several ways. First, it is different in that it allows the programmer to define a syntax that is different than what most languages are designed with. Plus Programming includes two syntactic levels, which is different than other S-expression languages such as Scheme, Prolog and Pcre. Also, Plus Programming can be used with a variety of programming languages, including Fortran and C++, making it useful in developing software and applications using different programming languages.

Plus Programming is also very useful because it allows the programmer to create small programs which are easy to implement and allows you to write the program, test it, debug it, and then change it after you have created more than one program. It is also useful because it does not require you to write a complete program in advance. Instead, a program is written using a single expression and then interpreted. The meaning of a certain piece of information is given by the programmer, and it is then transformed into a series of bits which then interpret the expression.

Plus Programming is similar to other languages because it is similar in the way that it interprets programs. Unlike some languages, it has two main types of statements: an infix and a ext/postfix. The infix statement is like a traditional “do” statement, where the program’s result is a value. The ext/postfix statement is much like a traditional “return” statement, which returns the result of a program to the caller. A program is written in a single expression but is interpreted into multiple expressions, usually with the right syntax, like an array or a dictionary.

Another feature of Plus Programming is the use of an underlying type known as a Generic Type. This is a generic data type that provides values for the expressions. One can either write a single generic type or multiple generic types depending on the type of the expression being used. This type is known as a Lambda type.

Since the type system in Plus Programming is dependent on its underlying type, there are a number of places where an expression can be evaluated before being converted into a concrete value. An expression is only evaluated once before being returned by the interpreter. It is important for the type to be able to provide a suitable result and to provide an appropriate type of result.

Plus Programming is an interesting language because it is an extension of the C programming language and is based on S-expression, a programming language. This makes Plus Programming very easy to learn compared to many other languages such as Java, C++, or Python. Plus Programming is very similar to other languages in that it has two main types of statements: an infix and a ext/postfix. It also has an additional feature called a generic type which gives you access to the underlying data type, so that you can easily work with different types of values in the same expression.
