The *.INP files are used to link AnalytiCalc - PC for various sizes; it was linked typically in an overlay structure to run in 256K or more, and another flatter one to run in 320K or more. It can link flat also. The *.BAT files have compiling material for ms fortran (3.3 or thereabouts). Typically I had all files into a library PCC88.LIB and linked with the normal MSDOS LINKER.
