Example

The following example demonstrates the functionality of the KPROPCASE function:

length fullkana halfkana upper lower fullalpha $ 200;
length str1 str2 str3 str4 str5 str7 str8 $ 30 str6 $44;

lower = 'do-naxtutsu';  /* Doughnuts in Japanese Roman word. */
upper = 'DO-NAXTUTSU';  /* Doughnuts in Japanese Roman word. */
fullkana = unicode('\u30C9\u30FC\u30CA\u30C3\u30C4');
halfkana = unicode('\uFF84\uFF9E\uFF70\uFF85\uFF6F\uFF82');
fullalpha = unicode('\uFF24\uFF2F\uFF0D\uFF2E\uFF21\uFF38\uFF34\uFF35\uFF34\uFF33\uFF35');

str1 = kpropcase(fullkana, 'full-katakana,half-katakana');
if (halfkana EQ trim(str1)) then
  put str1= $hex14.;
str2 = kpropcase(halfkana, 'half-katakana, full-katakana');
if (fullkana EQ trim(str2)) then
  put str2= $hex22.;

str3 = kpropcase(fullkana, 'katakana,romaji');
if (trim(str3) EQ upper) then
  put str3=  ;

str4 = kpropcase(upper, 'romaji,katakana');
if (trim(str4) EQ fullkana) then
  put str4= $hex22.;

str5 = kpropcase(fullalpha, 'full-alphabet, half-alphabet');
if (trim(upper) EQ str5) then
  put str5=;

str6 = kpropcase(upper, 'half-alphabet, full-alphabet');
if (trim(str6) EQ fullalpha) then
  put str6= $hex46.;

str7 = kpropcase(lower, 'lowercase, uppercase');
if (trim(str7) EQ upper) then
  put str7=;

str8 = kpropcase(upper, 'uppercase, lowercase');
if (trim(str8) EQ lower) then
 put str8=;

RESULTS:
str1=C4DEB0C5AFC220
str2=8368815B83698362836320
str3=DO-NAXTUTSU
str4=8368815B83698362836320
str5=DO-NAXTUTSU
str6=8263826E817C826D826082778273827482738272827420
str7=DO-NAXTUTSU
