hi,
use () instead of [] STRUC1979.(j)

Hi,
I tried this code but got a santax error for .[j] when removing the
dot (.) I got an error about 'j':
fields = Tag_Names(struct)
OpenW, lun, 'C:\cgcp\data.txt', /Get_Lun
FOR j=0,N_Elements(fields)-1 DO $
PrintF, lun, fields[j], ': ', struct.[j]
Free_Lun, lun
Error:
IDL> PrintF, lun, fields[j], ': ', struc1979[j]
% Attempt to subscript STRUC1979 with J is out of range.
% Execution halted at: $MAIN$
with .j Error:
IDL> PrintF, lun, fields[j], ': ', STRUC1979.[j]
PrintF, lun, fields[j], ': ', STRUC1979.[j]
^
% Syntax error.

I'd try something like this:
fields = Tag_Names(struct)
OpenW, lun, 'C:\cgcp\data.txt', /Get_Lun
FOR j=0,N_Elements(fields)-1 DO $
PrintF, lun, fields[j], ': ', struct.[j]
Free_Lun, lun
Cheers,
David
