Purpose
Similar to the SEARCH function with a few differences.
Parameters
- x
- An expression which specifies the string in which to search for a character or bit that appears in another string.
- y
- An expression where a character or bit appears.
- z
- An optional expression which specifies the location in the string
x from which to start searching. It must have a computational type and is converted to Fixed Binary(31,0).
Description
SEARCHR does the same as SEARCH, i.e. it returns the first position in a string where a character or bit of another string appears. However, there are a few differences between them. With SEARCHR search is done from right to left and the default value for
z is LENGTH(x).
Examples
dcl s char (16);
dcl i fixed bin (15);
s = 'Newbury, England';
i = searchr (s, 'ry'); /* i = 7, ‘y’ found starting from the right */
