Re: Dynamic variable names

Ekin,

In the past, I have created an array containing all or some of the variables
in a file and created a loop, which would process them individually.

vars = (/x1,x2,x3,x4/)
nvars = dimsizes(vars) - 1

do n=0, nvars
  var = f->$vars(n)$

; process variable
  .
  .
  .
delete(var)
end do
