Flint 36 A3D

This document, titled 'FLINT 36 A3D: Description and Operating Procedures,' serves as a technical manual for the FLINT interpretive routine. FLINT is designed for the Digital Equipment Corporation PDP-1 to handle double-precision floating-point arithmetic, input/output operations, and elementary function evaluation. Originally developed in FRAP for lens design, it was translated into DECAL for broader compatibility. The document covers the instruction repertoire (floating operations), interpreter entry, data formats, subroutines for input/output and unfloating, and user-defined modifications, including instructions on creating a partially relocateable version.
