Hi,
(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
<snip>
File Organization: sequential
Record Format: stream-LF
Record Attributes: carriage-return
Maximum Record Size: 0
Longest Record: 32767
<snip>
*** 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.
