Don't know Lotus. No possibilities to change defaults there? ;-)

Because you wrote in your question:

| by a certain string and that string would the % string.| [...]
which, even after rereading it, says that you want
a) to lookup something _by_ the % string, and that means the % string must be
the hash key,
b) to lookup arrays, which means the hash values are multi valued
and

| 5 2005/02/05 21:13 305 100% -il-o-b----f sg F01004
the % string is not unique over data file, whereas the F... string looks like
being unique.
and
because it seemed to make sense for me looking up the data by the pct value.

Since only the second snippet populates a hash, I'd say the second is better.
