Thanks Gary.

Well... you're using pointers. If you want the actual "data" in
data[0] to be stored as names[0] (presumably without being a pointer),
then you would need to put data[0] as a single string variable. If it
is already (I don't know w/o looking at your data), then you're fine;
otherwise, I guess you could do something like names[0] =
strjoin(*data[0],'||') with the double pipe to indicate a line break
or somesuch.

thanks Gary. this is exactly what i want and works perfect. What about
the posterior case: names[0] = data[0]?
Cheers,

if the former:
names = 'data['+strtrim(indgen(n_elements(data)),2)+']'

I'm not sure exactly what you're asking... do you want a "names" array
where names[0] is the string 'data[0]'? Or do you want a names array
where names[0] = data[0]?
