       /STOCK=string

    Specifies the type of paper stock to be associated with the form.
    The string parameter can be a string of 1 to 31 characters,
    including the dollar sign, underscore, and all alphanumeric
    characters. If you specify the /STOCK qualifier, you must specify
    the name of the stock to be associated with the form. If you do
    not specify the /STOCK qualifier, the name of the stock will be
    the same as the name of the form.

    You can create any string that you want; however, when you are
    creating forms with the same stock, be sure that the /STOCK
    string is identical in all the DEFINE/FORM commands that refer
    to the same type of paper.

    If you are defining a number of forms to provide different
    formatting options, specify the same stock type for each form.
    Jobs that request any of these forms will print on the same
    queue. If you want to modify the stock string associated with
    a form, you can do this only if the form is not referenced by any
    job or queue.
