/*     XFRLUN     I   Logical unit of an open DAS transfer file. */
/*     BINFIL     I   Name of the binary DAS file to be created. */

/* $ Detailed_Input */

/*     XFRLUN   The Fortran logical unit number of a previously opened */
/*              DAS transfer file. */

/*              The file pointer should be positioned ready to read */
/*              the DAS file ID word. */

/*     BINFIL   The name of the binary DAS file to be created. */

/* $ Detailed_Output */

/*     None. */

/* $ Parameters */

/*     None. */

/* $ Files */

/*     See arguments XFRLUN, BINFIL. */

/* $ Exceptions */

/*     1)   If the DAS transfer file cannot be read, the error */
/*          SPICE(FILEREADFAILED) will be signalled. */

/*     2)   If the specified file is not a DAS file, as indicated by the */
/*          file's ID word, the error SPICE(NOTADASFILE) is signalled. */

/*     3)   If an error occurs while attempting to decode data in the */
/*          DAS transfer file, the error SPICE(BADDASTRANSFERFILE) will */
/*          be signalled. */

/*     4)   If the DAS file cannot be written, a DAS file access routine */
/*          will signal an error with an appropriate error message. */

/*     5)   The binary DAS file opened by this routine, BINFIL, is only */
/*          GUARANTEED to be closed upon successful completion of the */
/*          text to binary conversion process. In the event of an error, */
/*          the caller of this routine is required to close the binary */
/*          DAS file BINFIL. */

/* $ Particulars */

/*     Any binary DAS file may be transferred between heterogeneous */
/*     Fortran environments by converting it to an equivalent file */
/*     containing only ASCII characters called a DAS transfer file. */
/*     Such a file can be transferred almost universally using any number */
/*     of established protocols. Once transferred, the DAS transfer file */
/*     can be converted to a binary file using the representations native */
/*     to the new host environment. */

/*     This routine provides a mechanism for converting a DAS */
/*     transfer file created by DASBT, or an equivalent procedure, */
/*     into an equivalent binary DAS file which may be used with the */
/*     SPICE system. It is one of a pair of routines for performing */
/*     conversions between the binary format of a DAS file and the DAS */
/*     transfer file. The inverse of this routine is the routine DASTB. */

/*     Upon successful completion, the binary DAS file specified by */
/*     BINFIL will have been created. The binary DAS file that was */
/*     created will be closed when this routine exits. The DAS transfer */
/*     file will remain open, as it was on entry, and it will be */
/*     positioned to read the first line after the encoded DAS file data. */

/* $ Examples */

/*     Let */

/*        XFRLUN   be the Fortran logical unit attached to a DAS transfer */
/*                 file which is to be converted into its binary DAS */
/*                 equivalent. */

/*        BINFIL   be the name of the binary DAS file which will be */
/*                 created. */

/*     Then, the following subroutine call would read the DAS transfer */
/*     file attached to the Fortran logical unit XFRLUN, convert its data */
/*     into binary format, and write that data to the binary DAS file */
/*     which is being created: */

/*        CALL DASTB( XFRLUN, BINFIL ) */

/* $ Restrictions */

/*     1) This routine assumes that it is positioned ready to read the */
/*        DAS file ID word from the encoded text DAS file. */

/*     A DAS transfer file contains in an encoded form all of the data */
/*     from the original binary DAS file. This includes the reserved */
/*     record area, the comment area, and the character, double */
/*     precision, and integer data arrays as well. */

/*     Currently, the reserved record area has not been implemented, as */
/*     there is no need for it at this time. If, or when, the reserved */
/*     record area is implemented, this routine will need to be modified */
/*     in order to support it. See the code for details. */

/*     The data in the DAS transfer file are available as sequences of */
/*     small blocks of data. This is to provide a means for performing */
/*     some error detection when converting a DAS transfer file into its */
/*     binary equivalent. Each block of data is enclosed within begin and */
/*     end block markers which hold the count of data items in a data */
/*     block. When all of the data blocks for a data area have been */
/*     written, a total blocks line is read to verify that all of the */
/*     data has been converted. */

/*     The data in the DAS transfer file MUST appear in the following */
/*     order for this routine to work properly. */

/*           1) Reserved records (when/if implemented) */
/*           2) Comment area */
/*           3) Character data array */
/*           4) Double precision data array */
/*           5) Integer data array */

/*     If the data count for any of these DAS data areas is zero, */
/*     conversion proceeds with the next DAS data area in the list. */

/*     For example, suppose that we have a binary DAS file where there */
/*     are 0 reserved characters in the reserved record area, 5000 */
/*     comment characters in the comment area, and that the character, */
/*     double precision, and integer array counts are 0, 2300, and */
/*     6900, respectively. Then, the DAS encoded text file will contain */
/*     no reserved record data blocks, 2 comment data blocks, no */
/*     character data blocks, 3 double precision data blocks, and 7 */
/*     integer data blocks, in that order. */

/*     DAS encoded text file description. */
/*     ---------------------------------- */


/*     A brief description of the DAS encoded file format and its */
/*     intended use follows. This description is intended to provide a */
/*     simple ``picture'' of the DAS transfer file format to aid in the */
/*     understanding of this routine. This description is NOT intended to */
/*     be a detailed specification of the file format. */

/*     A DAS transfer file contains all of the data from a binary */
/*     DAS file in an encoded ASCII format. It also contains some */
/*     bookkeeping information for maintaining the integrity of the */
/*     data. The DAS transfer file format allows the full precision of */
/*     character, integer, and floating point numeric data to be */
/*     maintained in a portable fashion. The DAS transfer file format is */
/*     intended to provide a reliable and accurate means for porting data */
/*     among multiple computer systems and for the archival storage of */
/*     data. */

/*     A DAS transfer file is not intended to be used directly to provide */
/*     data to a program. The equivalent binary DAS file is to be used */
/*     for this purpose. In no way should any program, other than a DAS */
/*     binary <-> transfer conversion program, rely on the DAS transfer */
/*     file format. */

/*     To correctly understand the DAS transfer file description  the */
/*     reader should be familiar with the DAS file architecture. Items */
/*     enclosed in angle brackets, '<' and '>', are used to represent the */
/*     data which are to be placed at that position in the file. The */
/*     bookkeeping information which appears is represented exactly as it */
/*     would appear in a DAS transfer file. */

/*     Let */

/*        <BOF>  denote the beginning of the file */
/*        <EOF>  denote the end of the file */

/*     and */

/*        nresvb  denote the number of encoded reserved record data */
/*                blocks generated */
/*        nresvc  denote the total number of reserved record characters */
/*                in the  reserved record area of a DAS file */
/*        ncomb   denote the number of encoded comment data blocks */
/*                generated */
/*        ncomc   denote the total number of comment characters in the */
/*                comment area of a DAS file */
/*        nchrb   denote the number of encoded character data blocks */
/*                generated */
/*        nchrs   denote the count of characters in the DAS character */
/*                data array */
/*        ndpb    denote the number of encoded double precision data */
/*                blocks generated */
/*        ndps    denote the count of double precision numbers in the DAS */
/*                double precision data array */
/*        nintb   denote the number of encoded integer data blocks */
/*                generated */
/*        nints   denote the count of integers in the DAS integer data */
