Fortran compiler for mac to read program -
i'm using g77 compiler (on terminal type g77 filename.for ) on mac. can't read fortran program , can't modify program (very old program, not mine, , need output it). suggestion compiler read program?
here kind of error get:
android-ae71922e0bc4a747:~ jadecheclair$ g77 geomalb.for geomalb.for: in program `geometric': geomalb.for:61: accept *,fhaze 1 2 unrecognized statement name @ (1) , invalid form assignment or statement-function definition @ (2)
the accept
statement not part of fotran standard. non-standard extension , therefore program not fortran 77 program , cannot expect compilers compile it.
notably, g77 not support extension https://gcc.gnu.org/onlinedocs/g77/type-and-accept-i_002fo-statements.html modern successor of g77 - gfortran - not support either.
you can try intel compiler (costs money), oracle compiler (free linux, not available mac) or (much better) convert source code fortran changing accept
read
.
