Focal-8

The FOCAL-8 Programming Manual serves as a foundational guide for developers and operators using the FOCAL-8 interpreter. It provides detailed information on equipment requirements, the initial dialogue for system setup, and an extensive explanation of the FOCAL-8 language, including its command set, output formatting, floating-point operations, variables, and error detection mechanisms. The manual also functions as a reference for specific FOCAL-8 commands such as TYPE, ASK, WRITE, SET, GOTO, DO, IF, and others, facilitating efficient application development on compatible PDP-8 series computers.
