[ncl-talk] addfiles: selecting files with datestamp in filename

[Dennis Shea]

An additional method based on Kevin's reply:

files = *systemfunc*("ls wrfout_d01_2*")   ; *all* 'd01' files for the 2000s

*sqsort*(files)   ; sort into ascending order

name_start = "wrfout_d01_2016-12-01_00:00:00"

*ii* = *ind*(files.ge.name_start)
f  = *addfiles*(files(*ii*), "r") ; all file from 'name_start' onward

======
If you want a stop date then

name_last = "wrfout_d01_2016-25-01_23:59:59"

*kk* = *ind*(files.ge.name_start .and. files.le.name_last)
f  = *addfiles*(files(*kk*), "r")
