strScan Function

Searches a text string for an occurrence of another string.

int strScan(

    str _text1,

    str _text2,

    int _position,

    int _number)

Parameters

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.

Return Value

The position in the string at which the specified string was found; otherwise, 0.

Remarks

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.
