You must specify a format='(...)' statement with the READF command. In
your case thi swoul dbe something like

READF,file, time, data, format='(3X,i10,f9.3)'

Also, because time is a long variable, you may have to assign it to a
long value before you call READF, e.g. time=0L (well, you don't have to:
IDL converts it into a float if you don't. But this way you can save it
as a long variable if you like to).

Cheers,
Martin.
