Description
STRPOS() is the substring search function. It returns a number signifying the starting position of <expC2> in <expC1>. If the substring is not contained within <expC2> or <memofield>, then the function returns the value 0. The leftmost character of a string is in character position 1. The optional numeric expression <expN> is used to specify an offset position at which to start the search (starting from 1). The return value is based on the start of <expC1> regardless of the offset. The STRPOS() function is particularly useful in conjunction with the LEFT() or SUBSTR() functions for locating starting points for extracting text from a string.
Example
? at("is", "Recital is good") 9 cString1 = "is" cString2 = "Recital is good" ? at(cString1, cString2) 9
Products
Recital Server, Recital
