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
? strpos("Lianja is good","is") 8 cString1 = "Lianja is good" cString2 = "is" ? strpos(cString1, cString2) 8
