Inserts a marker tag into a display list.
void maketag(Int32 tag)
SUBROUTINE MAKETA(tag) INTEGER*4 tag
The maketag subroutine inserts a marker, or tag, at the current editing location of the currently open display list. The current editing position is usually at the end of the display list, if the display list was recently opened with the makeobj subroutine or editobj subroutine.
The current position can be maneuvered with the objdelete, objinsert, and objreplace subroutines. Tags can be used to help in the maneuvering through and editing of display lists.
There are two predefined tags, STARTTAG and ENDTAG, which mark the beginning and end of the display list. Tags should be unique within a single object; however, there is no restriction regarding uniqueness across different objects. Unique tags can be generated with the gentag subroutine.
Note: This editing subroutine itself cannot be added to a display list.
