Vikram,

you can play with the format keyword...
something like this:

print, a, format='(120(A,","))' ==> will put a comma after each value

or

print, a, format='(120A)' ==>will write by 120 cols.

So, in your case, just remove the loops...

PRINTF,lun,array, format = '(120A)'

You can even change the 120 by n_elements(array[*,0]) etc
