SCELBAL, short for SCientific ELementary BAsic Language, is a version of the BASIC programming language released in 1976 for the SCELBI and other early Intel 8008 and 8080-based microcomputers like the Mark-8. Later add-ons to the language included an extended math package and string handling. The original version required 8 kB of RAM, while the additions demanded at least 12 kB.
The language was published in book form, with introductory sections followed by flowcharts and then the 8008 assembler code. The book described ways to save more memory, turning off arrays for instance, and how the user could add their own new features to the language.
