BANCStar programming language

In computing, BANCStar is a specialist programming language for financial applications. The language is an internal language for the National Financial Computer Services, Inc (later Broadway & Seymour) BANCStar application, which is software to automate the operations of a bank branch.

The language resembles an esoteric programming language — the only legal characters are the numerals 0-9, the comma, the minus sign and the carriage return — but is used in real commercial applications. It was originally intended as generated code from a user interface-building tool — similar to bytecode rendered in ASCII — but due to limitations in the tool became a directly-programmed language in itself.
