Icon is a high-level programming language with extensive
|
|
|
|
|
facilities for processing strings and structures. Icon has
|
|
|
|
|
several novel features, including expressions that may produce
|
|
|
|
|
sequences of results, goal-directed evaluation that automatically
|
|
|
|
|
searches for a successful result, and string scanning that allows
|
|
|
|
|
operations on strings to be formulated at a high conceptual
|
|
|
|
|
level.
|
|
|
|
|
|
|
|
|
|
Icon emphasizes high-level string processing and a design phi-
|
|
|
|
|
losophy that allows ease of programming and short, concise pro-
|
|
|
|
|
grams. Storage allocation and garbage collection are automatic in
|
|
|
|
|
Icon, and there are few restrictions on the sizes of objects.
|
|
|
|
|
Strings, lists, and other structures are created during program
|
|
|
|
|
execution and their size does not need to be known when a program
|
|
|
|
|
is written. Values are converted to expected types automati-
|
|
|
|
|
cally; for example, numeral strings read in as input can be used
|
|
|
|
|
in numerical computations without explicit conversion. Icon has
|
|
|
|
|
an expression-based syntax with reserved words; in appearance,
|
|
|
|
|
Icon programs resemble those of Pascal and C.
