Fortran /align qualifiers

JKrucus — Thu, 18 Aug 2005 18:06:17 GMT

I am recompiling from source an old Fortran program, that includes an obsolete qualifier.
It had /align=(rec=pack,comm=natu)
Now its /align=(comm=(pack,nomulti),reco=natu)
but the data does not align correctly.

Does anyone know the modern equivalent of the old /align qualifiers?
Thank you.

are u using a 32 bit OVMS or 64 bit?
if 64 bit then the "reco=natural" will cause problems.

I'd expect:

/ALIGN=(RECORD=PACK,COMMON=NATURAL)

to work. Note that:

/ALIGN=(REC=PACK)

will NOT work because they keyword "REC" is considered ambiguous.

Note that (COMM=(PACK,NOMULTI),RECO=NATU) does the exact opposite of (REC=PACK,COMMON=NATURAL). I'm assuming you want common blocks packed and records naturally aligned.

All that said, it would be very much in your interest to modify your code so that EVERYTHING is naturally aligned.

If that doesn't help, please post the EXACT command that's failing and EXACT AND COMPLETE error messages.

Also give some detail about what you mean by "does not align correctly". Show us what you're declaring and how you want it aligned.

reco = rec did it. Thank you, all.
