The database structure has changed. A MemCom database is now composed of a directory containing 3 or more files:
A header file (ASCII text file).
One or more index files.
One or more data files.
This modification has no consequences on the applications with the
exception that in case of copying files the whole directory tree must
now be copied (UNIX cp -r instead
of cp command). MemCom
version 6 databases can be converted by means of the
MemCom tool mcconv7. Example: Convert a
MemCom version 6 database
demo.db to a MemCom
version 7 database:
mcconv7 demo.db
mcconv7 creates a database
demo.db.mc, mc being the extension
of MemCom 7 databases. The neutral file
demo.mc6.nf created by mcconv7 can
be removed after the conversion operation.
For compatibility reasons the (new) file identifier
handle and the (old) file unit
handle are the same, i.e one can open a database file
with the Fortran open function (or vice versa) and then pass the
identifier handle to a C API call like
mcDBgetSetArray.
