!DEC$ - Does it still exist?

[Randy_Stonesifer]

My old code has !DEC$ IF(bitsystem .eq. 64)  lines for conditional compiling.  I am trying to compile with the latest ivf version (2015) using the vf 2010 shell.  I see no info in the documentation about !DEC$.  Is it obsolete? If it is what is the best alternative?

Thanks,

Randy

See online documentation at https://software.intel.com/en-us/node/525780.

You may want to go through the main section on "Directive Enhanced Compilation" in detail.

Of course, if you can minimize your use of such directives and work with standard Fortran (use /stand compiler option for checking), it will help you greatly in the long term via a largely portable codebase.

Do you have "bitsystem" defined as a preprocessor variable? That's what the directive would look for, and this isn't one that is predefined.
