ff5c7fe0d5
Purpose:
Maintenance
Description:
* Added support for generic properties.
* Added support for time allocation properties.
* Added support for variable length datatypes (only datatypes based
on INTEGER, REAL and CHARACTER Fortran types are supported).
* added some missing functions
Solution:
I am checking in new Fortran APIs and their man pages to support
1.5 features listed above.
Not all APIs have tests yet. APIs were written in Fall 2002, and I am afraid
that I will loose the code or totally forget what I did if I wait longer. ;-)
Platforms tested:
arabica (fortran), eirene (fortran), modi4 (parallel, fortran)
