Header Section #!N #!EC #!N #!N The header section of a 
Data Explorer file consists of a sequence of Object definitions. Each 
Object definition consists of a sequence of clauses, beginning with an 
 #!F-adobe-times-bold-r-normal--18*   object #!EF clause. The clauses defining an Object can be 
in any order, except that the type and size information for 
an Array must be specified before the data if the data 
are imbedded in the header. A clause consists of a sequence 
of words separated by one or more blank spaces or new 
lines. Line breaks are not significant (except after the  #!F-adobe-times-bold-r-normal--18*   follows 
#!EF keyword, when data must follow on the next line). Multiple 
clauses can occur on one line, and a single clause can 
be split across lines. The following sections describe each of the 
types of Objects that can be defined. In these descriptions, the 
 #!F-adobe-times-bold-r-normal--18*   monospace #!EF font specifies literals;  #!F-adobe-times-medium-i-normal--18*   italics #!EF , non-literals; 
square brackets [ ], optional items; and a vertical list, alternatives. 
#!N #!N In the header section (and text data sections),  #!F-adobe-times-bold-r-normal--18*   
# #!EF is the comment character. All text from  #!F-adobe-times-bold-r-normal--18*   # 
#!EF to the end of the line is ignored. #!N #!N
