StringInStr occurrence Default = -1?

[AGlassman]

What am I missing here? The Help file clearly shows the default for occurrence = 1. But the "Default" keyword seems to be interpreted as -1.

ConsoleWrite( "AutoItVersion: " & @AutoItVersion & @CRLF )

Local $S = "ABCDABCD"

Local $Start =  StringInStr( $S, "AB" )
ConsoleWrite( "$Start       = " & $Start & @CRLF )

Local $EndOne       = StringInStr($S, "AB", Default, 1,       $Start +1 )
ConsoleWrite( "$EndOne      = " & $EndOne & @CRLF )

Local $EndDefault   = StringInStr($S, "AB", Default, Default, $Start +1 )
ConsoleWrite( "$EndDefault  = " & $EndDefault & @CRLF )

Local $EndMinusOne  = StringInStr($S, "AB", Default, -1,      $Start +1 )
ConsoleWrite( "$EndMinusOne = " & $EndMinusOne & @CRLF )

---------------------------------------------------------------------
AutoItVersion: 3.3.16.1
$Start       = 1
$EndOne      = 5
$EndDefault  = 1
$EndMinusOne = 1

you should probably see it the other way around,
not   Default = -1,
but   -1 = Default

e.g,:   GUICreate("MyGUI 1", 300, 500, -1, -1, -1, -1)

You're right, there is an issue. With StringInStr() I highly suggest to
- use numeric values and not the "Default" word
- not use @error which always returns 0 even when " invalid "start" or "occurrence" parameter given "

AGlassman,

You are confusing "default" (as in what value is used if the parameter is nor explicitly set) and the keyword "Default". I have explained the difference here:

All clear?

Thank you Melba23. I have added a "Default is not always default" section to my AutoIt Gotcha book.
