 Thank you for your time!
 I am using a windows machine, unfortunately (and not used to using
 linux/unix os)... I took a look again into gretl and hansl guides,
 but with join and/or append I could not find such an option. H 
This may be a stupid question, but why exactly is a value like 
4.13108e-312 problematic for gretl? Or to rephrase the question, can you 
be more specific on what actually doesn't work and what the error 
message is?
'join' is quite powerful, so I would be optimistic that something can be 
done with your data. But so far I haven't really understood the problem. 
Maybe you can provide a snippet of 5 or 10 lines of what your csv file 
really looks like and what you want to have as a result in gretl.
cheers,
