Purpose
Function to search a character string for the specified occurrence of a substring
Syntax
ATNEXT(<expC1>, <expC2> [, <expN>])
See Also
AT(), INLIST(), LEFT(), OCCURS(), RAT(), RIGHT(), STR(), STREXTRACT(), STRTRAN(), STUFF(), SUBSTR()
Description
ATNEXT() is a substring search function which returns a number signifying the start position of a specified occurrence of <expC1> in <expC2>. The <expN> specifies the occurrence of <expC1> in <expC2>. The ATNEXT() function returns the value 0 if the specified occurrence does not exist. If <expN> is not specified, ATNEXT() checks for the first occurrence of <expC1>.
The leftmost character of a string is in character position 1. The ATNEXT() function is particularly useful in conjunction with the LEFT() or SUBSTR() functions for locating starting points for extracting text from a string.
Example
? atnext("is", "The fact is that Lianja is good", 2) 26 cString1 = "is" cString2 = "The fact is that Lianja is good" ? atnext(cString1, cString2, 2) 26
Products
Lianja Server, Lianja
