INDEX::
Returns the starting position of the string y within string
x; returns 0 if y not present in x.
>>--INDEX--(--x--,--y--)------------------------------------
------------><
Verify::
Returns the first position in string 1 where any element in
string 2 is not in string 1.
If all characters in x are
contained in y, result is zero.
>>--VERIFY--(--x--,--y--)-----------------------------------
------------><
Example: IF VERIFY(NAME,ALPHABET) THEN...;
DCL MAINSTR CHAR(6) INIT ('ANUK ');
DCL SUBSTRG CHAR(2) INIT ('NA');
RTN = VERIFY(MAINSTR, SUBSTRG);
Default search starts from 1st position.
RTN=3
