Does Strukt help in this regard - below?
Not sure how to contact developer.
I am looking for an App to parse large text files (>5 million records at a time).
These define fields by the number of characters from the beginning of the string.
There may be 100 fields per record.
The parsing rules may change from month to month, so there needs to be flexibility.
So the ability to store and retrieve an array of parsing rules is important.
I don't have time to learn GAWK ...
