 Industrial Real-Time Fortran

Industrial Real-Time Fortran (IRTF) was developed, during the decade of 1970-1980, to augment the Fortran language with library bindings useful for process and device control, and I/O.Also included in IRTF was a set of bit-manipulation functions which were eventually incorporated into MIL_STD-1753 for Fortran-77, and later into Fortran-90.
