Case sensitivity in searches using @ON (which can be defined using the @SEARCH-OPTION statement) now applies independently of the @PAR LOWER setting. It also applies to the @ON formats 8 to 10. The behavior in the past had no justification and was confusing since @PAR LOWER simply determines the conversion of characters on input from the terminal and the display of lowercase characters in the work window.
In the past, if the MARK operand was not specified in the @ON statement (format 3) then hit lines were not marked in L mode. Now they are marked with 1 as in F mode. The previous behavior was inconsistent: there should be no subtle differences between L mode and F mode.
If a backward search is performed with @ON (R operand), then if a hit is found the position is now moved far enough to the left to prevent any further hit from extending into the preceding one. The previous procedure could sometimes lead to backward searches indicating different hits from forward searches.
No column range is now specified in the @RANGE statement. Since this column range had nothing to do with the range symbol that was defined with @RANGE and was only taken into account in the @ON statement, it has now been transferred to the @SEARCH-OPTION statement.
