Done.  We now have a casefilter structure to do this.

My thought was simply to write a function that takes a set of variables, a case, and an enumeration.  Depending on the enumerated value specified, it would return true if any of the variables were missing, or if all of the variables were missing, or always return false regardless.

This could be combined with your approach: my function is usable as one of your predicates if done properly.

My idea is to define a function type similar to

/* Return true if case should be skipped */
typedef bool (*skip_case_predicate_t) (const struct ccase *c);

... and then to add an argument to casefile_get_{destructive}_reader which is the predicate to determine if each call to casereader_next_{xfer} should skip a case.

I have an idea for helping out with this.  I'll write up a patch when I get a chance.

Most procedures have a /MISSING subcommand.  A common algorithm should be developed to implement this, rather than each command having to handle it.
