2261.0. "Yet more download questions." by SHARE::DOYLE () Wed Feb 22 1989 08:34

    When I downloaded stpics.arc the other day  and tried to dearc this
    file I received an error in checksum, and then arc aborted.
     The same thing happened with the file called Jessica.arc
    Both of these I downloaded twice to make shure it wasn't a bad
    download. 
    	They still did the same thing.
    	Also how do you dearc the IFF collections that have the "build"
    program in them. When I tried to dearc "IFF40-79.arc"(or something
    like that). It disolved into files called "File0","file1","File2",....
    and so on.
    	It also disolved something called "build" and "pack".
    	However running build didn't work.
    	Anyone familiar with these formats?
    							Thanks;

2261.1My turn...LOWLIF::DAVISThat's not a BUG, it's a FEATURE!Wed Feb 22 1989 12:3729

It depends on the what method of downloading you used (Kermit or Xmodem).
Get a copy of CVTARC from MDKCSW::DUA2:[DAVIS.AMIGA.TOOLS]CVTARC.EXE first.
To use it, define it as a foreign command.  ($CVTARC :==$your_dir:CVTARC)
These be the rules:

Kermit:  The file should be fixed length 512-byte format. (do a DIR/FULL
to find out.  If it is not, do $CVTARC V file.ARC.  This should fix it.

Xmodem:  The file should be Stream-LF format.  If it is not, do $CVTARC U
file.ARC.  Now it should work.

For these with the "build" in them, follow these steps:

1.  CD to where the .ARC file is.  (RAM: works best)
2.  ARC E file.arc BUILD (Get the build procedure from the arc)
3.  execute build dest:  (where dest: is DF1: or wherever you want it built)

Yell if this is gibberish or doesn't work!

2261.2MEMORY::BERKSONThink honk if you're a telepathWed Apr 05 1989 10:2110
    I am trying to download and run a small executable using Kermit.
    The original file was 128 byte fixed length so I ran CVTARC on it
    which made it variable length 510 byte max.  Will Kermit be able
    to handle this or is there something I can do to make the file 512
    byte fixed length? 
    
    I downloaded the 128 byte fixed length and that produced a "File is not
    an object module" error.  Thanks.

I recommend that you "$ CVTARC U filename" the original file, and then
KERMIT the result with "Kermit> SET FILE TYPE BLOCK" mode.  If you are
truely paranoid, do the "$ CVTARC U filename" then do a "$ CVTARC V filename"
and do the transfer with Kermit's "SET FILE TYPE BIN" mode.

It seems that KERMIT is happy with any variable length file format.
What it really doesn't like is STREAM_LF.

Why don't these stupid programs all work with either???  A small
programming change would save many person years of explanation and wasted
download time.

    Kermit _is_ being changed.  Read the topic on "C-Kermit" in the
    HUMAN::KERMIT notesfile.  The problem comes from the difference
    between Unix-style stream-lf files and VMS-style files under RMS.
    The VMS C implementers chose to make a whole separate set of filesystem
    functions for RMS (read "standard on VMS") files.  The standard
    C library calls for reading and writing files run into trouble with
    RMS files.
    
    So far nobody has written a portability package that you could just
    hang on any vanilla Unix-flavor or Amiga-flavor C program and make
    it play with VMS files.  But an enterprising soul (hint) could
    undoubtedly take VMS C-Kermit, when it's released, and pull out
    just such a beast.

2261.6New XModem, perhaps?ATLS17::MCDONALD_JSurly to bed, surly to rise...Fri Apr 14 1989 17:4011
Hmm... have you guys tried the new XModem for VMS? (mentioned in a previous note
within the last month or so.)  I use it on the VAX side and HandShake2.12a on
the amiga side.  Doing Xmodem/OneK (Ymodem in HandShake), transfers are much
faster, error correction has so far proven foolproof, and I seem to be able to
transfer files regardless of their file type on the VAX.  (This seems kinda
strange to me, since XModem's supposed to choke up at the 510 byte variable
records... but it appears to work just fine.  Anybody else seeing this
behavior?)

2261.7New VMS XModem is the way to goCSOA1::LENDavid M. LenSat Apr 15 1989 23:394
    Yes, I am using the same combination.  I also, commented in another
    note that I no longer check the VMS file organization.  It definitly
    has made downloads alot easier.  In particular, I like the Ymodem
    Batch to transfer a bunch of files with a single command.

I think I got mine from CGOU01::DUA1:[PUBLIC.AMIGA.TOOLS]XMODEMVMS.BCK.
I'm not sure where I got my copy of Handshake2.12a, but it's probably all over
the place by now.
