Purpose

Function to search for a substring


Syntax

STRPOS(<expC1>, <expC2> [, <expN>])


See Also

AT(), ATNEXT(), INLIST(), LEFT(), OCCURS(), RAT(), RIGHT(), SET STRESCAPE, STR(), STREXTRACT(), STRTRAN(), STUFF(), SUBSTR()


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", "Lianja is good") 
         9
cString1 = "is"
cString2 = "Lianja is good" 
? at(cString1, cString2)
         9
