; Tags are a general mechanism of extensible data arrays for parameter
; specification and property inquiry. In practice, tags are used in arrays,
; or chain of arrays.

LABEL ti_SIZEOF
; constants for Tag.ti_Tag, control tag values

TAG_END equ 0 ; synonym for TAG_DONE
TAG_IGNORE equ 1 ; ignore this item, not end of array
TAG_MORE equ 2 ; ti_Data is pointer to another array of TagItems
; note that this tag terminates the current array

; If the TAG_USER bit is set in a tag number, it tells utility.library that
; the tag is not a control tag (like TAG_DONE, TAG_IGNORE, TAG_MORE) and is
; instead an application tag. "USER" means a client of utility.library in
; general, including system code like Intuition or ASL, it has nothing to do
; with user code.
