#!N #!N The following functions are available in this pull-down menu: 
#!N #!I0 #!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   New #!EF #!I50 #!N 
Resets the Data Prompter by setting all fields to their default 
values. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Open... #!EF #!I50 #!N Invokes a 
standard Motif file-selection dialog box that prompts for a choice of 
file. You can read in an existing General Array Importer header 
file, whether or not it was created with the Data Prompter. 
However, the Data Prompter does  #!F-adobe-times-medium-i-normal--18*   not #!EF support header files 
containing the data to be imported: the data is assumed to 
exist in a separate file. To read an existing header from 
a file that also contains the data to be visualized, the 
header should be written out to a separate file. #!N #!I0 
#!N  #!F-adobe-times-bold-r-normal--18*   Save #!EF #!I50 #!N Writes the Data Prompter header 
file out, using the current file name. The current file name 
is set by opening a file or by executing the  #!F-adobe-times-bold-r-normal--18*   
Save As... #!EF command. The Data Prompter will check the correctness 
of most aspects of the header file to be saved. Any 
problems are reported and the  #!F-adobe-times-bold-r-normal--18*   Save #!EF operation is terminated. 
You may then correct the indicated problem and save the header 
file again. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Save As... #!EF #!I50 #!N 
Is the same as  #!F-adobe-times-bold-r-normal--18*   Save #!EF except that you must 
specify a name for the header file. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   
Quit #!EF #!I50 #!N Terminates the Data Prompter application. It also 
gives you the option of saving any changes not already saved.
