Moving files to VMS from UNIX

This document is used to help in converting UNIX Vision Indexed Files into VMS RMS Indexed Files or moving binary sequential files from UNIX to VMS (steps 3 through 6).

There are several files mentioned in this document. Here is a description of each filename specified in the examples:

idx.unx	Vision indexed file
bin.unx	Unix binary sequential file
bin.fdl	File Definition Language for binary sequential file
bin.vms	Converted binary sequential file
idx.emp	Empty RMS indexed file
idx.fdl	File Definition Language for RMS indexed file
idx.vms	Converted RMS indexed file

UNIX

• Step 1: Get the record length
  
  Use VUTIL on the Vision indexed file to determine the maximum record length and make note of it for step 5.

    vutil -info <idx.unx>

• Step 2: Create a binary sequential file
  
  Use VUTIL to create a binary sequential file from the Vision indexed file:

    vutil -unload <idx.unx> <bin.unx>

• Step 3: Move the binary sequential file to VMS
  
  Use FTP in binary mode or VIO with the "p" option to move the binary sequential file from Unix to VMS.

VMS

• Step 4: Get the description of the record format and attributes
  
  Under VMS do a "DIRECTORY/FULL" on the binary sequential file. If you used FTP the record description should be:

  Record format:        Fixed length 512 byte records
  Record attributes:    None

  If you used VIO the record description should be:

  Record format:        Stream_LF
  Record attributes:    Carriage return carriage control

• Step 5: Create the FDL file for the binary sequential file
  
  Use the editor to create an FDL:

    edi/fdl <bin.fdl>

  A menu will appear with some options. Use the "Add" option to add the following file and record definitions:

    FILE
            ORGANIZATION         sequential
    RECORD
            BLOCK_SPAN           yes
            CARRIAGE_CONTROL     none
            FORMAT               undefined
            SIZE                 <record-size>

  NOTE: If you used FTP then <record-size> should be set to the maximum record length that was noted from the VUTIL command in step 1. If you used VIO then the <record-size> should be set to 0.
• Step 6: Convert the binary sequential file into VMS format
  
  Use the CONVERT command to change the binary sequential file into the VMS format described by the FDL for the binary sequential file:

    convert/fdl=<bin.fdl> <bin.unx> <bin.vms>

• Step 7: Create an empty indexed file
  
  Create an empty indexed file with a COBOL program

    runcbl <program>

  We will call the empty indexed file created from this program <idx.emp>.
• Step 8: Create the FDL file for the indexed file
  
  Use the ANALYZE command to create an FDL file from the empty indexed file:

    analyze/rms/fdl <idx.emp>

  We will call the FDL file created from this command <idx.fdl>.
• Step 9: Convert the VMS binary sequential file into an RMS indexed file
  
  Use the CONVERT command again to change the VMS binary sequential file into the VMS format described by the FDL for the empty indexed file:

    convert/fdl=<idx.fdl> <bin.vms> <idx.vms>
