I think I would use:
quote:
InStrRev( )

Action: Searches a string for the presence of a second string. The search is started from the end of the source string. Note that the offset returned is counted from the beginning of the source string.

Syntax: INSTRREV ("string1", "string2")

Parameters: String1

The string to search in.

String2

The string to search for.

Returns: ?
Offset of the first character of string2 found in string1, counted from the beginning of string1

0
String2 not present in string1



See Also: InStr( ), Left( ), Right( ), SubStr( )

Example: ; find last backslash in @CURDIR
$x = INSTRREV(@CURDIR, "\")
