Parameter |
Description |
|---|---|
|
_text1 |
The string in which to search. |
|
_text2 |
The string to find. |
|
_position |
The first position in the _text1 parameter to perform a comparison. |
|
_number |
The number of positions in the _text1 parameter for which to retry the comparison. If there is a minus in front of _number, the system searches the number of characters in reverse order from the specified position. |
The comparisons are not case sensitive.
Values for the _position parameter that are less than 1 are treated as 1.
The direction of the scan is controlled by the sign specified in the _number parameter. A positive sign indicates that each successive comparison will start one position closer to the end of the string. A negative sign indicates that each comparison will start one position closer to the start of the string.
