HP graphic driver working in GCG 8.0 or 8.1???

(OpenVMS 6.1/AXP, GCG 8.0)

Is the HPGL driver considered to be broken if it produces files that have
invalid RMS attributes? 

When we set up graphics like:

 Plotting Configuration set to:

       Language: HPGL
         Device: HP7550
  Port or Queue: HELICAL.HP

 Using a paper size of A4.

Then run a program, for instance, helicalwheel, the resulting file is not
in valid stream-lf format: 

$ anal/rms helical.ps
        File Organization: sequential
        Record Format: stream-LF
        Record Attributes:  carriage-return
        Maximum Record Size: 0
        Longest Record: 32767
***  VBN 1:  Last stream record does not contain a delimiter.
Unrecoverable error encountered in structure of file.

The file in question isn't very big, here is a DUMP showing the
tail end of it:

Virtual block number 5 (00000005), 512 (0200) bytes

 1B3B4641 3B505303 51424C3B 34393635 5694;LBQ.SP;AF;. 000000
 00000000 00000000 00000000 0000292E .).............. 000010
 00000000 00000000 00000000 00000000 ................ 000020

No "OA" (LF), just like anal/rms said.

(And yes, the longest record size value is wrong too, but that's
a different problem, not of GCG's making.)

Even with the invalid RMS it was still possible to get this file through
hp2pict on a Mac by moving it with FETCH set to force the type to TEXT.
