Hi,

you have to know *exactly* what it is the file before you start reading
it, i.e. the number and type of each and every variable within the
file. However, this seems to be the case as it looks as if you get the
long and fix variables well out of the file. As for the strings, I'd
suggest reading them as byte arrays and then converting them to string.
Mind, however, that you need to know the exact number of characters
within each string variable. Thus, it is not enough to know "there is a
string followed by a long number", but you need to know "there is a
string with 5 characters, followed by ..."

The IDL lines would then be

b = bytarr(5)
readu, lun, b
str_var = string(b)

Cheers,

Peter
