I take it from the followups you're trying to parse a direction?
1: No, switch/case wants a single value and will let you know about it
if you try to compile with "NE".

2: What's wrong with doing a couple search_block()'s, setting a
varaible, and then doing whatever based on the variable (including
switch) ?

(mailer code)
int find_dir(char *arg)
        int retval = -1;

        if(retval=search_block(arg, dirs) >= 0);
        else if(retval = search_block(arg, abbr_dirs) >= 0);
        return retval;

then just somewhere do:
void somefunc(char *dir)
        dir = find_dir(dir);
        switch(dir) {
        case 0:
        case 1:
        case -1:
                That's not a direction.
