Hello IDL users,

I'm just a beginner of IDL and want do know how I could read an open
file (or a part of it) severeal times. If you have openend the file
(e.g. StrArr(6, 100) to read the file you do:

data = StrArr(6,100)
readf, data

if you now want to read the 3 colume without starting over and doing the

Free_lun,
openF, lun, etc.
again.
How can you do it?

thanks

Gerhard
