Re: List command and daily average over years

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Piyatida,
When your data is multi-dimensional, the LIST command chooses an output
format so as to be able to fit the data into a fixed record length in 
the ASCII
output file or terminal listing. You can use LIST/FORMAT=  to set your own
output format, but this is not always convenient because with this 
qualifier you
don't get the automatic header for the data.  Using loops to list data 
for each
location or each time is another way to do it.  This is the sort of 
thing you might do:

yes? REPEAT/L=1:30  (LIST /x=75:90/y=30:35 var)
  or
yes? let xx = x[gx=var]
yes? let yy = y[gy=var]
yes? REPEAT/L=1:30  (REPEAT/x=75:90 (LIST/noheader xx; 
LIST/nohead/y=30:35 yy, var)

For your question about daily averages, see if this FAQ does the kind of 
thing you
want:  "How can I compute a daily climatology for a time series?"
