May be a silly question! How do I read a second file based on the info
in the first file? rewinf unit5 or do i need a script file to bring in
both files first?

If you're through with the first file, you could simply close it and
reuse the file number to open the second. If not, open the second file
with an unused file number and proceed.

I did the following, after reading the first file [from default unit
5, I rewound and closed the unit and tried opening the same unit to
read the second file and got this compiler error!
rewind 5
CLOSE (UNIT = 05, ERR = 9904)

open (unit=5,filename=fn2)

Whether it appears to "like" it or not, _strongly_ suggest following
Richard M's suggestion to change to something greater than 10.

There quite easily could be a problem here that is being masked by the
use of the preconnected unit and until eliminate that possible problem
speculating on others seems futile.

If fixing that doesn't resolve the issue, you'll need to post a more
complete description of the problems including any errors, the OPEN and
READ statements and the definitions/declarations of all pertinent
variables, at a minimum...

Oh, and do it for and and all files not expecting to read/write to a
preconnected unit, not just one instance...

To the OP,

FWIW, I use the f95 code below to grab a lun for file I/O. I've used it for years with no
problems but I haven't tested it too hard (e.g. no opening lots and lots and lots of files
to see where (if?) I get a -1 return value). Note that I start my search at lun=10 (nice
round numbah.)
