[ncl-talk] Using loadscript within a do loop

[Luke Osburn]

Hi,

The do loop that I use loads a sequence of .hdf files and I need to run
about several hundred lines of code on it. The only alternative that I can
think of is to have literally a do loop with several hundred lines of code
in it. Surely there has to be a better way?

Cheers
Luke
