[ncl-talk] Question about using curl instead of wget in system call

[Dennis Shea]

Use:

*http://www.ncl.ucar.edu/Document/Functions/Built-in/str_get_dq.shtml*
<http://www.ncl.ucar.edu/Document/Functions/Built-in/str_get_dq.shtml>
=========================================================================
dq = *str_get_dq*()

HTTP = "
http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p25.pl?file=gfs.t00z.pgrb2.0p25.f240&all_lev=on&all_var=on&subregion=&leftlon=15&rightlon=50&toplat=50&bottomlat=15&dir=%2Fgfs.2018082200
"

CURL = "curl -s "+ dq+HTTP+dq +" -o junk"
*print*(CURL)

*system*(CURL)
