[ncl-talk] Selecting same date

[Dennis Shea]

If the text files are structured like the example file (date grouped
together).
Please look at the printed output.
Basically, it is a book-keeping issue.

--
 diri = "./"
  fili = "test_vanucia.txt"
  pthi = diri+fili

  asciifile = asciiread( pthi, -1, "string" )
  nlines    = dimsizes( asciifile )

  dates = str_get_field( asciifile(1:nlines-1), 1, " " )  ; skip 1st line
  print(dates)
  ndates= dimsizes(dates)

  inew = ind(dates(0:ndates-2).ne.dates(1:))              ; index values
  print(inew)

  ngroup = dimsizes(inew)
  iStrt  = 0
  iLast  = inew(0)

  diro   = "./"

  do ng=1,ngroup
     print("---")
     print(""+asciifile(iStrt+1:iLast+1))

     filo = dates(iStrt)+".txt"
     ptho = diro+filo
     system("/bin/rm -f "+ptho)                  ; remove any prexisting
file
     asciiwrite(ptho,asciifile(iStrt+1:iLast+1))
     if (ng.ne.ngroup) then
         iStrt = iLast+1
         iLast = inew(ng)
     end if
  end do
