[Info-vax] Architecture specific code in VMS Fortran

[Tom Wade]

Hello,

I've checked out the HP Fortran manuals for compiler directives in code that can select based on the 
architecture (VAX/Alpha/IA64).  It seems the CDEC$ IF DEFINED stuff is the way to go, but although 
it describes how to define and test variables, I can't see a list of predefined variables such as 
the current architecture.  I want to do something like

CDEC$ IF DEFINED (VAX)

  <code to be compiled only if on VAX>
CDEC$ ENDIF

Any small examples ?

Thanks

Tom Wade
