Example program using wide characters.. The following program uses wide
characters, and works for both HP-15 and EUC encoding schemes. The
program folds characters strings. A field size is specified defining the WIDTH
for text displayed on the screen. As a given string is printed, any character
whose display would fall outside the designated text region is "folded" onto the
next line.
For instance, if the
WIDTH = 5
and the string is
0123456789,
the result is:
01234
56789
