Thanks, but still i do not have an idea how i can load this array from a file 
if i do not know how many items it contains.

 i AS Integer
    myFile AS File
    newCars AS Object[]
    tmpcar AS CCar
    newCars = NEW Object[]
    FOR i = 0 TO cnt // if i do not know cnt ...
        tmpcar = NEW CCar
        newCars.add(tmpcar)
    NEXT
    IF Dialog.OpenFile() THEN RETURN
        TRY OPEN dialog.Path FOR READ AS myFile
            FOR i = 0 TO cnt
                newCars[i].ReadFrom(myFile)
            NEXT
        CLOSE myFile

I took it back.

I would appreciate this.
I think it is easier to have it in one sight.
Maybe like this
<h1>File Management</h1>
<h2>Keywords</h2>
 COPY
 KILL
 LINK
<h2>Functions</h2>
 Access

 Exist
