Recompilation of old Fortran programs - why does it give an error?

Question

Fortran

I have Fortran programs written around 1993-1998. They were compiled using the Fortran77 compiler. Now I'm trying to recompile them on Simply Fortran 3.2 in order to work with them under Windows 10. I get some strange messages, for example, in the OPEN statement, the FORM='BINARY' entry is considered an error by the compiler, thus excluding the possibility of processing binary files. The error message looks like this: Error: FORM specifier in OPEN statement at (1) has invalid value 'BINARY' How can I solve this problem? Thanks in advance for your help
