Error executing com script -

I am using VMS 7.3-2 and have logged in as system and tried to execute a com script and got the following error (I am new to VMS please give me details on how to retrieve information in case you need more info)

%RMS-W-RTB, 5511 byte record too large for user's buffer

I did the steps remotely as well as from the terminal and yet I got the same error. I am also posting below terminal charactericts incase that is helpful

Input: 9600 LFfill: 0 Width: 80 Parity: None

Re: Error executing com script -


The first step should be to turn on DCL verification (SET VERIFY). This will log each and every command executed by the command file.

Doing a DIRECTORY/FULL command on the file that is causing the error is a start.

Also, doing a DUMP/RECORD/ASCII would be a good thought.

The file (or a file that it is operating on), would appear to have a long record. This may be for any number of reasons.

Re: Error executing com script -

First, please go read the OpenVMS User's Guide. It is entirely your obligation to learn how to use the basics of the platform and its command interface, and that manual provides you with the basic knowledge required. You'll save yourself a whole lot of time here, and frustration.

The OpenVMS manuals (and other manuals) are here:


Here, you're going to have to debug the DCL command procedure that's tossing out the error.

Whether this is related to the terminal settings or not is not in evidence. Usually, this isn't the terminal settings. See the DCL command HELP /MESSAGE/FACILITY=RMS RTB for the basics of the error itself. Here's the output from that:

RTB, 'nnn' byte record too large for user's buffer

Facility: RMS, OpenVMS Record Management Services

Explanation: A record that was retrieved from a file by an RMS $GET
operation within an application program is too large for the
buffer provided by the application. The status value (STV)
field of the RAB contains the size of the record that is too
large; the returned record is truncated to the size of the
user buffer.

User Action: Ensure that the RMS record structure and the RMS file
attributes on the associated RMS file meet the requirements
of the application. If they do, the application program must
be rebuilt or reconfigured to provide a buffer large enough to
read the failing record from the file. alternatively, the size
of the failing record must be reduced to fit into the buffer
provided by the application.

The basic DCL debugging sequence here involves some examination of the DCL procedure itself, and particularly looking at the DCL to see how to enable verification. With some procedures, you can issue SET VERIFY at the command line and then invoke the procedure. You'll then see what the procedure is doing, and usually get a better idea of what is tossing the error. With other DCL command procedures, you have to add a SET VERIFY or an f$verify(1) inside the procedure, usually near the top.

Then you have to figure out what command is failing. And why.

In summary, you use the knowledge gained in reading the OpenVMS User's Guide to understand the basics of DCL debugging and DCL command syntax and potentially the trigger. Or at least toward having the particular command(s) that are failing, so that somebody can look at it.

Re: Error executing com script -

Thanks Robert,
Here is some of the info

Set verify - did not give any more results as to any specific line etc. The same output as before

Re: Error executing com script -

Your CSLGMENU.COM license PAK menu DCL command procedure was probably incorrectly transferred from where ever you got it from; what's shown there looks to be corrupt. (This part of the procedure's settings is not likely correct: /Record format: Variable length, maximum 0 bytes, longest 5511 bytes/)

Get a fresh copy. If the file went through a Windows or Unix box, it may well have gotten corrupted -- Windows in particular will default to assuming a .COM file is an image, and will select the wrong transfer mode. This above and beyond the usual lack of support for the OpenVMS sequential file formats.)

Or prepare to unsnarl a corrupted sequential file. That's more work.

Re: Error executing com script -

thanks Hoff,
I will check on that I did transfer as ASCII from Windows to VMS. Usually for other com files this problem does not occur.

I will look into this. thanks!

Re: Error executing com script -

Look at the 2nd byte in the 3rd dump line (counting out from the middle).
And the 2nd to last byte in line 7 (2nd from left). Those are linefeed characters, meant to be line terminators.
The 5511 is a numeric interpretation of what shout be the string "$!"

So what have here is a STREAM-LF file, used as a veriable length file.

To fix this issue:

Now try again.

"That was easy!"

Re: Error executing com script -

If you're going to migrate files through a Microsoft Windows box or most any other non-OpenVMS box, the I'd suggest use of the zip "-V" mechanisms and a zip archive to protect the files. Don't toss raw OpenVMS files around.

When the archive file arrives on the target box, then use unzip.

zip and unzip aren't in the base OpenVMS distribution, but they are present on the Freeware distribution in the 000TOOLS area. And they should be in your own local installation, and they should be used for tasks such as this.

There are newer versions available over at Info-Zip.org, too.
