The following items commonly appear as syntactic variables in the syntax diagrams featured in this section.

<alphanumeric character>

Any one of the characters A through Z or 0 through 9.

<Boolean-valued attribute>

                   └─ ON ──<family name>─┘

Specifies a particular directory.

<EBCDIC string character>

Any one of the 256 EBCDIC characters except the double quotation mark (").

<family name>

  ┌◄────────────────────┐
──┴─/17\─┬─ <letter> ─┬─┴──────────────────────────────────────────────┤
         └─ <digit> ──┘

Identifies a disk family.

A family is a logical means of grouping mass storage devices together so that they function as one logical unit. Specification of the family name indicates a named native-mode disk pack, and any continuation packs, whose name is the specified family name. A file with a KIND attribute value of DISK or PACK refers, by default, to the family with the family name DISK.

DUMPALL maintains a list of the attributes it supports, but it uses MCP routines for verification of attribute values. For example, as new DENSITY values are added to the MCP (to support new tape drives), these values are automatically supported by DUMPALL.
