---++ Description:

This subroutine is called to write data to a file stream previously opened for WRITE or APPEND access via [[0LASubrStreamOpen][.STREAM OPEN]].

The first two parameters are required, and the subroutine will CANCEL if they are are not all received.

&lt;write_buffer&gt; contains the data to be written (Required). This subroutine can write lines up to a maximum of 32000 characters. The &lt;line_termination&gt; character you specified when you opened the file will automatically be appended to your data.

&lt;stream_name&gt; is the name of the previously opened stream (Required).

&lt;binary_write_length&gt; is an optional parameter and is only applicable if the file was opened in binary mode (5.4.4 & up). If the file is opened in binary mode and this parameter is not passed, it will default to the length of &lt;write buffer&gt;. The &lt;write_buffer&gt; field will be padded with spaces if necessary. If the length of &lt;write_buffer&gt; is greater than 32000, only the first 32000 bytes will be written. If &lt;binary_write_length&gt; is larger than the size of &lt;write_buffer&gt; then the actual length of &lt;write_buffer&gt; will be used.
