Snowball (programming language)
This article's factual accuracy may be compromised due to out-of-date information. (April 2021)
The basic datatypes handled by Snowball are strings of characters, signed integers, and boolean truth values, or more simply strings, integers and booleans. Snowball's characters are either 8-bit wide, or 16-bit, depending on the mode of use. In particular, both ASCII and 16-bit Unicode are supported. Like the SNOBOL programming language, the flow of control in Snowball is arranged by the implicit use of signals (each statement returns a true or false value), rather than the explicit use of constructs such as if, then, and break found in C and many other programming languages.
The name Snowball was chosen as a tribute to the SNOBOL programming language, with which it shares the concept of string patterns delivering signals that are used to control the flow of the program. The creator of Snowball, Dr. Martin Porter, "toyed with the idea of calling it 'strippergram' ", because it "effectively provides a 'suffix STRIPPER GRAMmar' ".
