Hi, I'm trying to read an ASCII file using a structure as follows: openr, 1, asciifile.txt nrows=70 template={a:' ', mm:0, dd:0, hr:0, mn:0, sc:0} data=replicate(template,nrows) readf, 1, data close, 1 The problem is that all five fields (a, mm, dd, hr, mn, sc) get dumped into data.a. Is there a simple way to read structures when the first field is a string? Thanks
