You can use standard abbreviations for switch names.
Switches can appear before or after the input file name.
See Section 4.5.21 for more information about the -unroll switch. Note When you use kapf to process a file, you must set the Digital Fortran compiler and linker switches appropriately. For this reason, Digital recommends that you use kf77 whenever possible, as kf77 automatically sets the compiler and linker switches correctly.
