; This UDF "udfArrayItemize" converts a given dim-1 array into an itemlist
; with each item separated by delimiter character.
;
; Example: strMyItemList = udfArrayItemize (arrMyArray, @TAB)
; Creates an itemList from array.
;
; Note:
; This UDF supports only dim-1 array.
; An array element which is not initialized has a Vartype=0 (undefined).
; Therefore an empty item will be appended to target itemlist.
