[gradsusr] Opening multiple grib files with template option

[Mubashar Dogar]

Dear GraDS users,

I am using grads-2.0.a7.oga.3 version. I wanted to open many grib
files with template option in descriptorCTL, but my grib files doesn't
match with any template option given in GrADS page. Could you please
help me out?
My data is 6 hourly in each day and files name is given below:

ei_oper_an_pl_19890101_19890104.grib
ei_oper_an_pl_19890105_19890108.grib
