Hi,

I have a problem when trying to use "if then else" statments i my script it
gets the following error mensage: "fatal:Conditional statements (if and do
while) require SCALAR logical values, see all and any functions". I've tryed
to use the functions "all" and "ismissing" to solve it but it didn't work.
What can i do to solve this?! Could anyone help me?!

Thanks!

Rosa
P.S.: I'm sending a part of the script bellow!
====================================================
begin

file_in = addfile("/home/rosa/CCSM3/dados_paulo/

attributes
psnm = file_in->psnm
uvel = file_in->uvel

  if (.not.all(ismissing(umrl)) .and. umrl .gt. 100) then
  ur = 100
  else
  ur = umrl
  end if

print(ur)
