[Sunhelp] ?: Fortran77 v3.0 can't support on Solaris 7

[Wonkyu Chang - Sun Korea SE]

Dear expert,

IHAC having Fortran77 v3.0 compiler.
Now, he's going to upgrade OS into Solaris 7.
But, as you know, Fortran77 v3.0 can't support on Solaris 7 

Then, which version does he need to upgrade his compiler?

Thanks,
WK Chang
