As Jean has already pointed out, you'd have to organize things
differently to use MAX() and MIN() here. However, it's far simpler to
avoid MAX() and MIN() altogether.

max_x = file1_xmap[1] < file_xmap[1]
min_y = file1_ymap[0] > file_ymap[0]
max_y = file1_ymap[1] < file_ymap[1]

It all looks pretty confusing if you're used to a language (there are
quite a few) where '<' and '>' are comparison operators, but in IDL the
corresponding comparison operators are called 'lt' and 'gt'. The '<' and
'>' operators return the minimum and maximum, respectively, of their
operands.
