[ncl-talk] Looping through strings to build new variable names

[Alan Brammer]

Mike,

You may be better looking into the list functionality.   Take a look at the
ncl-talk email from k griffin a few days back, and the echo function that
was posted.  You could push the variable into a list and add the station
name to it as well.   Then retrieve it back out of the list based on the
station name.

The other way would be rather than having new variables, add the data as an
attribute to another variable.

alldata = True
alldata@$station+"_MaxT"$ = new((/dimsizes(dates(i*k:i*k+i))/), "float")

however you can't have attributes on attributes so not all of that would be
transferable.

Why do you want uniquely and logically named variables inside the code?

Good luck buddy.
