.STREAM READ

Line: 24 to 24

<stream_name> is the name of the previously opened stream (Required).

Changed:

<

<read_length> is the number of bytes to read (optional). If not passed, or if blank/zero is passed, it will read up until the line termination character specified in .STREAM OPEN. If passed shared, it will return the number of characters actually read, however, you should set it back to zero before the next GOSUB --- .STREAM READ, otherwise this subroutine will only read that number of characters.

<read_length> is the number of bytes to read (optional). If not passed it will read up until the line termination character specified in .STREAM OPEN to a maximum of 32000 characters. If passed shared, it will return the number of characters actually read, however, you should set it back to 32000 before the next GOSUB --- .STREAM READ, otherwise this subroutine will only read that number of characters.

If --- .STREAM READ contains 'Data was truncated', it means the <read_buffer> field you passed was not large enough to contain all the data that was read. If --- .STREAM READ contains 'EOF', then there is no more data to be read.
