The command line is: 
               	 
            
 
            	 dfconv [-d|-D|-f|-F] [-s|-S] profile-fname [input-fname] [output-fname]
 
            	 where the parameters are: 
               		
               
 
                  		   
                  			 
                  - -d, -D 
                     			 
                  
- Stops the display of the data file convert console messages.(Optional.) 
                     			 
                  
- Do not specify if -f or -F is already specified. 
                     			 
                  
- -f, -F 
                     			 
                  
- Only the fixed text output is displayed; no dynamic updates displayed to the console after each record is processed. (Optional.)
                     
                     			 
                  
- Do not specify if -d or -D is already specified. 
                     			 
                  
- -s, -S 
                     			 
                  
- Skips DBCS checking. This option only has an effect when set in an environment where the locale uses a code page with a DBCS
                     encoding. Only set this option if you are running within a DBCS locale, but are converting a file that only contains SBCS
                     data. Setting this option in such circumstances, will significantly improve the performance of the conversion. 
                     			 
                  
 
                  		   
                  			 
                  - profile-fname 
                     			 
                  
- The name of the profile file that contains the details of the task you need to perform. 
                     				
                     Note: This file must have a 
                        				  .PRO extension. If you specify a file with any other extension, DFCONV attempts to locate a profile file using the specified base-name
                        and the 
                        				  .PRO extension. 
                        				
                      
 
                  		   
                  			 
                  - input-fname 
                     			 
                  
- The name of the input file (optional). 
                     			 
                  
 
                  		   
                  			 
                  - output-fname 
                     			 
                  
- The name of the output file (optional). 
                     			 
                  
 The input and output file-names are optional as they can be extracted from the profile file. If you specify file-names on
               the command line as well as in the profile file, those on the command line take precedence. 
               	 
            
 
            	 
             After conversion, the operating system error level 
               		 is set to non-zero if an error occurred during conversion. If you are running the conversion from a batch file, you can
               interrogate this to determine what action to take after the conversion.
