- ; 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.

- STRUCTURE TagItem,0
- ULONG ti_Tag ; identifies the type of the data
- ULONG ti_Data ; type-specific data
- LABEL ti_SIZEOF
-
- ; constants for Tag.ti_Tag, control tag values
- TAG_DONE equ 0 ; terminates array of TagItems. ti_Data unused
- 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
- TAG_SKIP equ 3 ; skip this and the next ti_Data items
-
- ; differentiates user tags from control tags
- TAG_USER equ $80000000
-
- ; 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.
