This is standard FORTRAN.
You can even have a line like
3*,4*2.0,4,5,6
read(*) a ! with a(10) = real, say
Then the first three elements of a will be left unchanged.
The n* is called a "null input field": the above is equivalent to
,,,2.0,2.0,2.0,4,5,6
but IDL won't understand that either.
If this is likely to be a common problem, perhaps you should write a PERL
procedure to translate the data.
