The Pennsylvania State University developed a "Dual Autocoder Fortran Translator" (DAFT) compiler for the IBM 7074 in the 1960's which made it extremely easy to write (within a single program) lines of autocoder instructions freely interspersed with lines of Fortran code. This allowed symbolic machine instruction level coding within a higher level Fortran program, which was especially useful for optimizing the speed of inner loops, or for making use of the IBM 7074's unusual decimal word architecture.{{cn}}
