IBM SC34-5764-01 WORDINDEX, WORDLENGTH, WORDPOS (Word Position), WORDS, XRANGE (Hexadecimal Range)

WORDINDEX
 WORDINDEX(string,n) 
returns the position of the first character in the nth blank-delimited word in string or returns 0if fewer than
nwords are in string. The nmust be a positive whole number.
Here are some examples:
WORDINDEX('Now is the time',3) -> 8
WORDINDEX('Now is the time',6) -> 0
WORDLENGTH
 WORDLENGTH(string,n) 
returns the length of the nth blank-delimited word in string or returns 0if fewer than nwords are in string.
The nmust be a positive whole number.
Here are some examples:
WORDLENGTH('Now is the time',2) -> 2
WORDLENGTH('Now comes the time',2) -> 5
WORDLENGTH('Now is the time',6) -> 0
WORDPOS (Word Position)
 WORDPOS(phrase,string
,start
) 
returns the word number of the first word of phrase found in string or returns 0if phrase contains no words
or if phrase is not found. Multiple blanks between words in either phrase or string are treated as a single
blank for the comparison, but otherwise the words must match exactly.
By default the search starts at the first word in string. You can override this by specifying start (which must
be positive), the word at which to start the search.
Here are some examples:
WORDPOS('the','now is the time') -> 3
WORDPOS('The','now is the time') -> 0
WORDPOS('is the','now is the time') -> 2
WORDPOS('is the','now is the time') -> 2
WORDPOS('is time ','now is the time') -> 0
WORDPOS('be','To be or not to be') -> 2
WORDPOS('be','To be or not to be',3) -> 6
WORDS
 WORDS(string) 
returns the number of blank-delimited words in string.
Here are some examples:
WORDS('Now is the time') -> 4
WORDS(' ') -> 0
XRANGE (Hexadecimal Range)
 XRANGE(
start ,end
) 
returns a string of all valid 1-byte encodings (in ascending order) between and including the values start
