By default, searches by FIND, REPLACE, and alt-F5 (SEARCH) key are
case-sensitive, i.e. 'Survo' and 'SURVO' are not identical in searches.

There are two alternatives to make these searches case-insensitive:
1. If the command line in FIND and REPLACE or the starting edit line in
   alt-F5 has '#' in the control column, the search is always
   case-insensitive.
2. By setting the system parameter search_caps=1 in the SURVO.APU file
   these searches become case-insensitive when the Caps Lock in the
   keyboard is on. Otherwise searches are case-sensitive.
