The object to which the label refers (e.g. IMAGE, TABLE, etc.) is denoted by a statement of the form: ^object = location in which the carat character (^, also called a pointer in this context) indicates that the object starts at the given location. In an embedded label, the location is an integer representing the starting record number of the object (the first record in the file is record 1). In a detached label, the location denotes the name of the file containing the object, along with the starting record or byte number if there is more than one object. For example: ^IMAGE_HEADER = ("XXXXX.IMG",1) ^IMAGE = ("XXXXX.IMG",3) indicates that the IMAGE object begins at record 3 of the file XXXXX.IMG, in the same directory as the detached label file. Below is a list of the possible formats for the ^object definition. ^object = n ^object = n ^object = ("filename.ext") ^object = ("filename.ext",n) ^object = ("[dirlist]filename.ext",n) ^object = ("filename.ext",n) ^object = ("[dirlist]filename.ext",n) where n is the starting record or byte number of the object, counting from the beginning of the file (record 1, byte 1) indicates that the number given is in units of bytes filename is the upper-case file name ext is the upper-case file extension dirlist is a period-delimited path-list of parent directories, in upper case, that specifies the object file directory (used only when the object is not in the same directory as the label file) The list begins on directory level below the root directory of the CD-ROM. '[dirlist]' may be omitted when the object being described is located either in the same directory as the detached label or in a sub-directory named 'LABEL', located one level below the CD-ROM root directory.
