Name
       DDIS - Digital Data Interchange Syntax / ISO ASN.1 (DDIS/ASN.1) files

Description
       DDIS/ASN.1 files conform to Digital's Digital Data Interchange Syntax.  DDIS conforms to syntaxes that can be defined within the specifica-
       tions of International Standards Organization Abstract Syntax Notation One (ISO ASN.1), but is not itself an  implementation  of  full  ISO
       ASN.1 syntax.

       DDIS/ASN.1 files conform to the DDIS/ASN.1 syntax.  The DDIS/ASN.1 syntax is itself used to define other syntaxes.  The following are among
       the syntaxes that are subsets of DDIS/ASN.1:

	      DDIF   Digital Document Interchange Format

	      DTIF   Digital Table Interchange Format

	      DOTS   Data Object Transport Syntax

       Files that conform to one of the DDIS/ASN.1 family of syntaxes are described as DDIS/ASN.1 files.  More specifically,  however,	the  files
       are typed according to a particular DDIS/ASN.1 syntax.  For example, a file that conforms to the DDIF syntax is a DDIF file, and is identi-
       fied by the command as a ddis/ddif file. The command includes the string ddis/ as a part of its output if a file belongs in the	DDIS  fam-
       ily.

ctod(1) 						      General Commands Manual							   ctod(1)

Name
       ctod - combine DDIS objects into DOTS format

Syntax
       ctod [ -x ] object.ddis

Description
       The  command  combines  a  DDIS encoded object into a Data Object Transport Syntax (DOTS) format, which is written to standard output.  The
       object may contain references to other DDIS files.  The purpose of is to create a single file from multiple references to other	files,	in
       order to transfer or move DDIS objects from one location to another.

       object.ddis  is a file name, or a minus sign (-) for standard input.  If a minus sign is specified, or if no file name is present, standard
       input is read.  The named object and its external references, if any, are combined into a DOTS data stream which  is  written  to  standard
       output.

       Because a DOTS stream contains binary data, output should be redirected to a file or a pipe.

Options
       -x   Specifies that is to DOTS encode the input file without resolving any external references present in the file.  This option is for use
	    only with files containing no external references.

Restrictions
       The only DDIS object types supported in this release are DDIF and DTIF.

Diagnostics
       The exit status is 0 if all files were combined successfully and 1 if any of the files could not be combined.  Consult `standard error'	to
       see what files failed, and why.

       If  the	-x  option  is	used  and contains any external references, returns an error status of 1, and writes an error message to `standard
       error'.
