Searches a text string for an occurrence of another string.
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 sign in front of the _number parameter, the system searches the number of characters in reverse order from the specified position. |
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.
-

strScan ("ABCDEFGHIJ","CDE",10,-10); //Returns the value 3.
