2. SAS FUNCTIONS INDEX / INDEXC / INDEXW
 These functions search for the char / substring in a
string
 It returns the values such as 0,1,2,…
 It doesn’t return null value
 It always search from left to right
 It returns value of position of first occurance
 These are case sensitive functions

3. SAS FUNCTIONS INDEX / INDEXC / INDEXW
• INDEX:
 search for first occurance of substring
Syntax:
INDEX(string, substring)
EX: A=“hi,where is he”
Index(A,”he”)  5

4. SAS FUNCTIONS INDEX / INDEXC / INDEXW
• INDEXC:
Search for the first occurance of any one of char
value of subsring
Syntax:
1. INDEXC(string,”char1”,”char2”,”char3”…)
2. INDEXC(string,”char1char2char3…..”)
Ex: A=“hi,where is he”
INDEXC(A,”he”)  1
Here it searches for first ocurance of “h” or “e”

5. SAS FUNCTIONS INDEX / INDEXC / INDEXW
• INDEXW:
search for first occurance of specific word
Syntax:
INDEXW(string, word)
Ex: A=“hi,where is he”
INDEXW(A,”he”)  13
INDEX and INDEXW are similar, the difference being that
INDEXW looks for a word, while INDEX simply searchs for
the designated substring.
