In a system with several pubsets, each pubset has its own TSOSCAT file catalog. Each of these catalogs is uniquely identified by its catalog ID (catid). The catalog ID (catid) is part of the file name.
A file name has the format: :catid:$userid.filename
catid | Catalog identifier. This has a length of 1-4 characters and must be enclosed in colons. |
userid | User identification under which the file is cataloged. The user identification must be preceded by a $ sign. It has a maximum length of 8 characters and must be concluded with a period. |
filename | Name of the file as entered in TSOSCAT. The file name component, including all periods (designating partial qualification), must not exceed 41 characters. |
A fully qualified file name, consisting of catalog ID, user ID and file name, may have a total length of up to 54 characters:
up to 4 characters | Catalog ID |
2 character | Colons as delimiters before and after the catalog ID |
1 character | $ signifying the beginning of the user ID |
up to 8 characters | User ID |
1 character | . (period) used as delimiter between user ID and file name |
up to 41 characters | File name, including all periods for partial qualification; max. length depends on the length of the catid and userid |
