This is starting to make some sense to me.  Unfortunately the data for
a given year spans 12 monthly directories (data/nc/197901,
data/nc/197902, etc.).  Therefore I would like to be able to say:

foreach year in [1979:2011] {
  file thisYear[]<filesys_mapper;
    location= @strcat( "data/nc/", year, "*"),
    pattern= @strcat( "narr-a_221_", year, "????_??00_000.single.nc")>;
. . .

("*" glob at the end of location) but this does not work, nor do I
expect it to.  I am sure that location is meant to be a literal, not a
glob.  That's why I thought I needed a regex.  Is there a work-around
other than the obvious rearrangement of the data?
