Purpose
Conversion of ABAP Lists spool requests from non-Unicode to Unicode
codepage. ONLY ABAP Lists spool requests might be converted. It's better
to launch a conversion in background, in case of large spool requests
(about 10000 lines and more). There might be a problem with VERY large
spool requests (180000 lines and more).

Selection
selection of spool requests numbers and usernames. at least one of
those parameters should be specified.

Output
The converted data is written to same spool request, the copy of
original request is created and it's number is displayed at results
screen.
