PSS®E-31 and all future planned releases use the Intel Visual FORTRAN (IVF) compiler. % t0 w1 H: Q' O4 gUser-written software used with PSS®E-31 (e.g. Conec, Conet, user-written dynamics models, or / @5 |" g" V9 N) z$ g0 c" o# [
programs that call USRCAS) must be compiled with Intel Visual FORTRAN (IVF) 9.1 or later (the & s# @# H8 ^! k% ?10.1 compiler is recommended).
