Compability issues with F66

[HC_I_]

Hello, I'm trying to compile some sources coded that come from Unisys basic mode with F66 compatibility. I have create the makefile with the flags -f66 -nowarn, but I got a lot of syntax issues related to types, initialization, use of pseudo-functions,...etc. Maybe the reason of that is because I'm not using the right flags, so please could anyone give me any advise or help me with it?

Thanks in advance!

The -f66 flag is not well adapted to Unisys extensions from Fortran 66.   It is designed to allow IBM style f66 + extensions to work.  If you want advice, you will need to show some representative examples.  If the code was designed to work only with the Unisys compiler and depend on a 36-bit word size, it may be rather difficult.  I've never seen a compiler for other than a 18/36-bit machine which was designed to support such extensions, even by setting flags.

In short, your problem most likely is that your source code is not Fortran 66, so setting flags for some incompatible dialect of f66 isn't likely to help.
