Re: how to run zipexe

You normally get that message if the file is
not complete. You might also get it if the
file was transferred using an ASCII FTP
transfer instead of binary.

In either case, you probably need to download
the file again.

DIRE /SIZE to check the size.

DIRE /FULL to check the file attributes. A
binary FTP transfer should give you "Record
format: Fixed length 512 byte records". An
HTTP transfer will probably give you "Record
format: Stream_LF, [...]". Either one should
work if you get the whole file.

Looks like your zip is working, but the file is broken.

Typical reasons:
1) FTP in Ascii/Text mode instead of Binary
2) Partial transfer (after disk quota exceeded or dropped link).

It won't help with this problem, but note
that a self-extracting archive can be
unpacked using a normal (external) UnZip
program, too.

When the self-extracting archive was made
using UnZip older than 5.52 (like 5.42,
here), self-extraction of a large file may
be noticably slower than extraction using an
UnZip 5.52 (or newer) program, which has
some VMS-specific I/O speed improvements.

One word of warning, though.

You _can_ use a Windows- or Unix based ZIP program to unzip the files and FTP them (BINARY!) to VMS but that may renbder thie files unusable on VMS because the attributes and, in some cases, the internal structure are ruined.
Best you try to get the latest version of UNZIP (and ZIP).

One thing to keep in mind if you FTP zip's to a VMS box (ANY box, in fact): it should ALWAYS be done in BINARY mode; one step wrong and the file is broken beyond repaisr.
