In EBCDIC:
'<.A>' = '<.A. >' -> 1 /* true */
'<><><.A>' = '<.A><><>' -> 1 /* true */
'<> <.A>' = '<.A>' -> 1 /* true */
'<.A><><.B>' = '<.A.B>' -> 1 /* true */
'abc' < 'ab<. >' -> 0 /* false */
5. Word extraction from a string—“Word” means that characters in a string are delimited by an SBCS
or a DBCS blank.
In EBCDIC, leading and trailing contiguous SO and SI (or SI and SO) are also removed when words
are separated in a string, but contiguous SO and SI (or SI and SO) in a word are not removed or
separated for word operations. Leading and trailing contiguous SO and SI (or SI and SO) of a word
are not removed if they are among words that are extracted at the same time.
In EBCDIC:
W1 = '<><. .A. . .B><.C. .D><>'
SUBWORD(W1,1,1) -> '<.A>'
SUBWORD(W1,1,2) -> '<.A. . .B><.C>'
SUBWORD(W1,3,1) -> '<.D>'
SUBWORD(W1,3) -> '<.D>'
W2 = '<.A. .B><.C><> <.D>'
SUBWORD(W2,2,1) -> '<.B><.C>'
SUBWORD(W2,2,2) -> '<.B><.C><> <.D>'
Built-in Function Examples
Examples for built-in functions, those that support DBCS and follow the rules defined, are given in this
section. For full function descriptions and the syntax diagrams, refer to Chapter 14, “Functions,” on page
171.
ABBREV
In EBCDIC:
ABBREV('<.A.B.C>','<.A.B>') -> 1
ABBREV('<.A.B.C>','<.A.C>') -> 0
ABBREV('<.A><.B.C>','<.A.B>') -> 1
ABBREV('aa<>bbccdd','aabbcc') -> 1
Applying the character comparison and character extraction from a string rules.
COMPARE
In EBCDIC:
COMPARE('<.A.B.C>','<.A.B><.C>') -> 0
COMPARE('<.A.B.C>','<.A.B.D>') -> 3
COMPARE('ab<>cde','abcdx') -> 5
COMPARE('<.A><>','<.A>','<. >') -> 0
Applying the character concatenation for padding, character extraction from a string, and character
comparison rules.
COPIES
In EBCDIC:
COPIES('<.A.B>',2) -> '<.A.B.A.B>'
COPIES('<.A><.B>',2) -> '<.A><.B.A><.B>'
COPIES('<.A.B><>',2) -> '<.A.B><.A.B><>'
