In NLS mode,
folds strings to create substrings using character display positions.
Syntax
FoldDP (string, length [ , mapname ] )
string is the string to be folded.
length is the length of the substrings in display positions.
mapname is the name of a character set map to use for
the formatting. If mapname is not specified, the current default for
the project or job is used.

The FoldDP function
is suitable for use with multibyte character sets. If NLS is not enabled,
the FoldDP function works like an equivalent Fold function.
