Brief_I/O

 
   Variable  I/O  Description 
   --------  ---  -------------------------------------------------- 
   fname      I   Name of a DAS file to be opened. 
   handle     O   Handle assigned to the opened DAS file. 
 

Detailed_Input

 
   fname       is the name of a DAS file to be opened with write 
               access. 
 

Detailed_Output

 
   handle      is the handle that is associated with the file. This 
               handle is used to identify the file in subsequent 
               calls to other DAS routines. 
 

Parameters

 
   None. 
 

Exceptions

 
   1)  If the input filename is blank, the error SPICE(BLANKFILENAME)
       will be signaled.
 
   2)  If the specified file does not exist, the error 
       SPICE(FILENOTFOUND) will be signaled. 
 
   3)  If the specified file has already been opened, either by the DAS
       file routines or by other code, the error SPICE(DASOPENCONFLICT)
       is signaled. Note that this response is not paralleled by
       dasopr_c, which allows you to open a DAS file for reading even
       if it is already open for reading.
 
   4)  If the specified file cannot be opened without exceeding the
       maximum allowed number of open DAS files, the error
       SPICE(DASFTFULL) is signaled.
 
   5)  If the named file cannot be opened properly, the error
       SPICE(DASOPENFAIL) is signaled.
 
   6)  If the file record cannot be read, the error
       SPICE(FILEREADFAILED) will be signaled.
 
   7)  If the specified file is not a DAS file, as indicated by the
       file's ID word, the error SPICE(NOTADASFILE) is signaled.
 
   8)  If no logical units are available, the error will be signaled by
       routines called by this routine.
 

Files

 
   See argument `fname'. 
 

Particulars

 
   Most DAS files require only read access. If you do not need to 
   change the contents of a file, you should open it using dasopr_c. 
 

Examples

 
   1)  Open the existing DAS file TEST.DAS for writing. 
 
          dasopw_c ( "TEST.DAS", &handle );
 

Restrictions

 
   None.
