#79294 - 2002-11-08 03:04 PM FOR EACH behavior
Sealeopard Sealeopard KiX Master Registered: 2001-04-25 Posts: 11165 Loc: Boston, MA, USA	Folks: Please run the script below and comment on the bahavior. This behavior is not pertinent to KiXtart 4.12 RC-1 but seems to be a more general problem. code: break on cls ;segment 1 dim $array[2] $array[0]='Array Entry 0' $array[1]='Array Entry 1' $array[2]='Array Entry 2' for each $element in $array ? 'Element = '+$element next ; segment 2 dim $array $array='String Entry 0' for each $element in $array ? 'Element = '+$element next I think that the result of segment 2 is incorrect. It should either raise an error because the variable $array is of type string and not type array since the documentation states it has to be an array or collection. Alternatively, or better, preferably, it should treat the string type as an pseudo 1-element array and proccess it accordingly, thus resulting in an output of 'Element = String Entry 0'. _________________________ There are two types of vessels, submarines and targets.

And I requested that SPLIT("string","") return an array of single letters some time ago. code: break on cls ;segment 1 dim $array[2] $array[0]='Array Entry 0' $array[1]='Array Entry 1' $array[2]='Array Entry 2' for each $element in $array ? 'Element = '+$element next ? "@error @serror" ; segment 2 dim $array $array='String Entry 0' for each $element in $array ? 'Element = '+$element next ? "@error @serror" [ 08.

Howard Bullock Howard Bullock KiX Supporter Registered: 2000-09-15 Posts: 5809 Loc: Harrisburg, PA USA	but @error & @serror are not reset to zero when "For each" executes correctly. If there is not an intervening function that sets @Error to zero the same "-1 Expected an object reference. [-1/FFFFFFFF]" error is repeated. [ 08.

Doofus Doofus Lurker Registered: 2005-10-13 Posts: 1	My problem is that even if I DIM the array (DIM $array[10]), if I populate it with only one entry ($array = "element1"), I still encounter the same problems. The only good workaround I've come up with is to tag a blank element onto the array ($array = "element1", ""), then wrap the contents of the FOR EACH with an IF: Code: FOR EACH $element IN $array IF $element ? $element ENDIF NEXT Which is pretty ugly and a hassle.....
