1 CVT
 CVT input-file output-file

 This  program  allows the user to change the format of a sequential file. 
 This  is  useful  when  using  file serving packages which map files onto
 fixed  or  undefined  format  files , but are in reality using linefeeds,
 carriage returns or both to delimit records. 

 The program works by creating a file of identical length to the original,
 copying all record information to the output file's FAB,  and altering it
 according to the qualifiers specified.   The file is then copied in block
 mode, regardless of the structure of either file. 

2 Parameters
 input-file

 Specifies  the  input  file  to read.  This file is read in block mode to 
 produce  an  output file based on the structure of the input file and the 
 qualifiers specified on the command line

 output-file

 Specifies the output file to be created.

2 Command_Qualifiers
/CARRIAGE_CONTROL
 /CARRIAGE_CONTROL=cc-specifier

 Use  the  /CARRIAGE_CONTROL  qualifier  to  specify what type of carriage 
 control  the  output  file  is going to have.  cc-specifier can be one of 
 the following:

    CARRIAGE_RETURN Standard carriage return carriage control
    FORTRAN         FORTRAN carriage control
    PRINT           Print file carriage control
    NONE            No carriage control

 Note  that  /CARRIAGE_CONTROL=PRINT requires that the file format be set 
 to VFC.   Also,  some stream formats default to carriage return carriage 
 control if /CARRIAGE_CONTROL=NONE is specified.

/FORMAT
 /FORMAT=format-specifier

 Use  the /FORMAT qualifier to specify the new format of the output file.
 format-specifier can be one of the following keywords:

    FIXED           Fixed length records
    STREAM          Stream file using CR/LF pairs to delimit records
    STREAM_CR       Stream file using carriage returns to delimit records
    STREAM_LF       Stream file using line feeds to delimit records
    UNDEFINED       Undefined format file, ie no record structure
    VARIABLE        Standard variable length record file
    VFC             Variable with fixed control field

 Note  that if format-specifier is set to FIXED, the /SIZE qualifier must
 be specified.  If VFC is specified, the control field length will be set 
 at two bytes.

/SIZE
 /SIZE=record-size

 The  /SIZE qualifier specifies the record size to use.  This is required 
 for  fixed  length  record files.  The value will appear in the "maximum 
 record size" field of non-fixed files.

/STREAM
 /STREAM

 The  /STREAM  qualifier  causes CVT to search the first part of the file 
 for  a  carriage return/line feed pair, single carriage return or single 
 line  feed  and  format  the  output  file accordingly.   If no carriage
 control  characters  are  found,  the  output  file  is  written  in the 
 same format as the input file.

 The /STREAM and /FORMAT qualifiers are mutually exclusive.
