Fix file attributes of VMS BACKUP savesets

OpenVMS (all hardware platforms
The command procedure below sets the RMS file attributes of a file to those expected for a VMS BACKUP saveset. If you FTP a BACKUP saveset, the file attributes will be mangled.  If you use ASCII transfer, all is lost.  But, if you use Binary transfer, the attributes can be fixed by this procedure.  N
Usage Notes
This procedure does not work on VAX/VMS versions 5.5 and prior because it uses the SET FILE/ATTRIBUTES command.

$! P1  is the specification of the BACKUP saveset
$! This procedure resets the record format and record
$! length attributes of a BACKUP saveset -- savesets
$! can get "broken" during certain sorts of file
$! transfers -- such as FTP.  This procedure reads the
$! (undocumented) saveset record attributes directly
$! out of the target file.
$! First render the saveset readable, and implicitly
$! check that the file exists.
$ Set File -
    /Attributes=(RFM:FIX,MRS:512,LRL=512,ORG=SEQ,RAT=NONE) -
$ Open/Error=whoops/Read BckSaveset 'p1'
$ Read/Error=whoops/End=whoops BckSaveset Record
$ Close/Nolog BckSaveset
$! Find the blocksize from within the record...
$ BlockSize = 0
$ BBH_L_BLOCKSIZE = %x28*8
$ BlockSize = F$CVUI(BBH_L_BLOCKSIZE, 32, Record)
$ If BlockSize .lt. 2048 .or. BlockSize .gt. 65535
$ Then
$   Write sys$output "Unexpected block size"
$   Goto whoops
$ Else
$   Set File /Attributes=(RFM:FIX,LRL='BlockSize', -
       MRS='BlockSize',RAT=none) -
$ endif
$ exit
$ Write sys$output "Error"
$ exit
