Listing Element Attributes

Most element attributes can be listed for a beam line or table. The elements for which the attributes should be listed are selected by a SELECT command. The attributes are specified by the command

ATTLIST,LINE=name,FILE=name,COLUMN={string,string,...,string};

Most element attributes can be listed as columns. At present, MAD-9 does not recognize ATTRIBUTES or attributes of a BEAMBEAM element. Example:

 SELECT, LINE=LIN1, FULL;
 ATTLIST, LINE=LIN1, FILE=TERM,
   COLUMN={NAME,CLASS,KEYWORD,TYPE,LENGTH,K0L,UNKNOWN};

This may produce the following output:

@ TYPE     %s  ATTRIBUTE
@ LINE     %s  LIN1
@ DATE     %s  11/10/1999
@ TIME     %s  14.08.14
@ ORIGIN   %s  MAD_9.3
@ COMMENT  %s  ""
* NAME CLASS KEYWORD TYPE L K0L UNKNOWN

As it can be seen, empty strings are printed as the word ``Null''.
