Dataset Structure

The dataset structure may be specified in Backus-Naur Form as:

<Dataset> ::= <TEST> <Object> { <Object> }

<Object>  ::= <OBJDESC>  <AUDIT>  [ <INFOSPEC> ]  
              { <COMMENT> } <DIMSPEC0> <DIMSPEC1>  <DIMSPEC2>  
              [ <DIMSPEC3> ] <DESCRIP0> <Dimgroup1> 
              { <Dimgroup1> } <Dimgroup2> { <Dimgroup2> } 
              [ <Dimgroup3> { <Dimgroup3> } ]
              { <BADVAL> } { <Procgroup> }  { <Auxgroup> }
              <Regdata> | <Packdata> | <Compdata>

<Dimgroup1> ::=  <DESCRIP1>  <DESCVAL>  [ <DESCSUP> ]  
                 { <Descgroup> }

<Dimgroup2> ::=  <DESCRIP2>  <DESCVAL>  [ <DESCSUP> ]  
                 { <Descgroup> }

<Dimgroup3> ::=  <DESCRIP3>  <DESCVAL>  [ <DESCSUP> ]  
                 { <Descgroup> }

<Descgroup> ::=  <DESCRIP>  <DESCVAL>  [ <DESCSUP> ]  

<Procgroup> ::=  <PROCSPEC>  [ <PROCFORM>  <PROCVAL> ] 
                 { <PROCDUP> }

<Auxgroup> ::= <AUXSPEC> <AUXRANGE> <AUXVAL> [ <AUXSUP> ] 

<Regdata> ::= <REGDAT> { <REGDAT> }

<Packdata> ::= <Packgroup> { <Packgroup> } <PAKDAT> 
               { <PAKDAT> }

<Compdata> ::= <Compgroup> <COMPDAT> { <COMPDAT> }

<Packgroup> ::=  <PAKSPEC>  [ <PAKFORM>  <PAKVAL> ]

<Compgroup> ::=   <COMPSPEC>  <COMPLEN> 
                  [ <COMPFORM>  <COMPVAL> ]

where <UPPERCASE> indicates a record type, <Mixedcase> represents a group of records, braces (``{}'') indicate zero or more occurrences of what they enclose, brackets (``[]'') indicate zero or one occurrences of what they enclose, and a vertical bar (``|'') indicates a mutually exclusive choice among options.
