type
o ASCII
Arranges characters according to ASCII sequence. ASCII is the
default sequence and need not be specified.
o EBCDIC
Arranges characters according to EBCDIC sequence. The
characters remain in ASCII representation; only the order
is changed.
o Multinational
Arranges characters according to Multinational sequence, which
collates the international character set. When you use the
Multinational sequence, characters are ordered according to
the following rules:
- All diacritical (accented) forms of a character are given
the collating value of the character (A', A", A` collate as
A).
- Lowercase characters are given the collating value of their
uppercase equivalents (a collates as A, a" collates as A").
- If two strings compare as equal, tie-breaking is performed.
The strings are compared to detect differences due to
diacritical marks, ignored characters, or characters that
collate as equal although they are actually different. If
the strings still compare as equal, another comparison is
done based on the numeric codes of the characters. In this
final comparison, lowercase characters are ordered before
uppercase.
Care should be taken when sorting or merging files for further
processing using the Multinational sequence. Sequence checking
procedures in most programming languages compare numeric
characters. Because Multinational is based on actual graphic
characters and not on the codes representing those characters,
normal sequence checking does not work.
cs-name
Arranges character keys according to the named sequence, which
must be a collating sequence defined in an NCS library.
High-performance Sort/Merge: The high-performance Sort/Merge
utility currently supports only the ASCII, EBCDIC, and
Multinational collating sequences.
