3452.0. "VLTjr problems" by YUPPY::PEGLEY () Wed Feb 07 1990 08:52

    I have just got hold of a copy of VLTjr4428 that was set up on 
    a 2000 with 2 floppy drives and 1meg memory.
    
    When I tried to run it on my 500 with single floppy and 0.5 meg
    it got to the point of loading VLT as a backgroung task. It then:-
    
    Asked me to insert volume DF1 in any drive. I formatted and named
    a disk as DF1 and put it in.
    
    It then gave an error MENU-NOSUCH PROTOCOL, LIBS:xprzmodem.library
    
    It then gave me CANNOT OPEN SCREEN and dropped back to the workbench
    screen.
    
    I even created a directory called LIBS on DF1 and copied xprzmodem
    to it as the error came up when DF1 was in the drive.
    
    Does VLT only work on dual floppy configurations?, do I have enough
    memory to run it? should I download VLT and unzoo it in case there
    is a setup command file to set config parameters? or have I just
    missed something obvious!
    
    I am loathe to download as i have a 1200baud modem and only Xmodem.
    My estimate to transfer it would be 2 hours.
    
    By the way, is there an easy way to convert VMS record lengths to Amiga
    blocks to get an idea of transfer times. I can tell the speed that
   blocks are being recieved at, but there seems to be no correlation to
    the VMS record size.

3452.1Change DF1: for DF0:VIVIAN::S_GOLDSTEINSteve G...DTN 847-5415 Wed Feb 07 1990 14:3914
    Hi Steve,
    	     Your problem is that the copy you have is setup for a 2 drive
    system (as you got it from Clive who got it via me)
    
    In the memu for downloads there is a command for changing default
    directories.. Change it from DF1: to DF0:
    
    This disk that you have copies a lot of file to RAM so change the
    startup-sequence file in the S: directory...(take out startup1)
    
    If you have any problems give me a call...

    Depends on what you're looking at.  When you get a directory showing
    file sizes on VMS, the sizes are in terms of 512 byte blocks.  (Record
    size, as shown by VMS, does not affect download times.)  So, a 100 block 
    file would be 100 * 512 = 51200 bytes.  File sizes on the Amiga are
    usually shown in terms of bytes.
    
    Normal XMODEM transfers data in fixed length 128 byte packets, newer
    variants such as YMODEM use 1024 byte packets.  Depending upon which 
    protocol you are using, you are probably 'seeing' data arrive in
    'blocks' of either 128 bytes or 1024 bytes at a time.  Some of the
    transfer programs display an estimated number of packets at the start
    of a download.
3452.3RMS HorrorsTLE::RMEYERSRandy MeyersThu Feb 08 1990 20:3321
Converting VMS file sizes to bytes as outlined in .2 provides a
reasonable estimate of download time, but it does overestimate
the file sizes sometimes.

Do a DIR /FULL of a file to find out the record format and record
attributes of the file.  If the record format is variable length,
the size of the file in blocks reflects the record size information
overhead.

VMS (or RMS, whoever you want to blame it on) does not store files
as pure data.  Instead, various record organizations are imposed
upon them.  Variable length records are stored as a two byte
record byte count followed by the data.  If the file has
a carriage control attribute, the ending carriage control
character (newline) that ends every line isn't stored.  Instead,
after reading a record, you assume you saw the indicated
end of line character.

Thus, figuring out the number of data bytes in a file can be
challenging.  Taking the number of blocks and multiplying by
512 gives a good rough guess, but it isn't perfect.
3452.4APR lib problemNAVIER::MELLITZMon Apr 02 1990 11:417
    I down loaded VLTjr last night. Unzoo it with out any indication
    of errors. When I run it I get an "error openning APR library".
    So I down loaded the REXXARPLIB and unzooed that... No luck so far.
    Anyone have any hints.
    
    Thanks,
    Rich

    Sounds like it might be asking you to have arp.library in the libs:
    directory. The arp.library file is available in ARP13.ZOO.

    re: -1
    
    Is that ARPPRO13.ZOO ro ARPREL13.ZOO? I can't seem to find ARP13.ZOO.
    
    Do I still need the arexx library?

3452.7DICKNS::MACDONALDWA1OMM 7.093/145.05/223.58 AX.25Mon Apr 02 1990 18:101
    Probably ARPREL13.ZOO (just a matter of where ya find it).
3452.8ARexx? APR?NAVIER::MELLITZMon Apr 02 1990 18:348
    Thanks,
    
      I've got a class to night. I'll try it tomorrow. 
    
      BTW, What is ARexx and how does it relate to VLTjr? It
      the APR library related to ARexx?
    
    G'day

    Hi,
    
    	Arprel113.zoo or whatever it is called is on wjg::amiga:arp*.zoo
    
    	Arexx is a seperate product not PD

3452.10look on FF308FRSOLD::ZIMMERMANNWer von Euch Kerls ist KowalskiWed Apr 04 1990 07:526
    If you're following the installation instructions coming with VLT/VLTjr
    you should have no problem installing the *.library-files.
    The complete set is on FF308 (latest version plus latest arp.library)
