Question

Does ACL "write" have a size limit?

Is there an established limit for the size of a text string written to a channel using the ACL write command? We have encountered a few instances when using the write command where this appears to be true, but I have found no documentation of this limit. To be clear, here is the line of code we are referring to:

write($channel, $text_string)

Our testing has shown that when $text_string is greater than 4,095 characters in length, the call fails.

We are running Arbortext v5.4 on UNIX.

Any suggestions would be appreciated.

Regards,
Tom

    Hi Tom--



    Yes, there is a limit to the length of strings that can be passed. The
    usual way to handle this is to write smaller chunks, e.g. to write each
    line as a separate operation. It's often done using an array of strings,
    where each element of the array is a line.



    If your string isn't line-based, you may just have to use arbitrary
    breaks, e.g. every 4000 chars, something like this:



    # write long string to output file

    local $content = $text_string;

    while (length($content)>0) {

    write($channel, substr($content, 1, 4000));

    $content = substr($content, 4001);

    }



    HTH.

    Thank you. We have implemented logic like that which you show below as a work around to the problem. I guess we will now think of it as the end solution.

    Thanks again for your swift response.
