Dear statalisters,

My current database(it's in .txt) has a typical line in the form :

cod1=time1   cod2=...  cod3=n   cod4=type1   cod5=quantity1
cod6=price1   cod4=type2   cod5=quantity2   cod6=price2

cod3=n (n=2 in this case, and n varies through lines) says that
following this code, that are 2 records, each of them starts with
cod4=type. For example:
cod4=type1   cod5=quantity1   cod6=price1         and
cod4=type2   cod5=quantity2   cod6=price2          are records.

I want to generate a new database in the form:

cod1     cod4      cod5         cod6
time1    type1    quantity1    price1
time1    type2    quantity2    price2

I think it's only possible to do that with Mata given the lenghs of
the lines, is it right?

Can anyone give me a direction?

Best regards,
