binary raster files in GrADS

Hi there - I'd first try open them with a remote sensing package eg
envi/arc/erdas etc which may be better suited to this than grads. I
suspect that the .bil extension may be a format specific to arc, though
it could also be band interleaved by line which would also not be
readable by grads.
    You may though be able though to create your own descriptor file
provided the data is in a grads readable format, from the information in
the header file, have a look  at the  section on descriptor files in the
    Good Luck
