    Function copyblob()
    Short Copies the (embedded) content of a BLOB field to a file or into an array
    Syntax COPYBLOB(blob : fielddesc; [file : STRING|VAR array : [BYTE|CHAR|INTEGER|TBITS|REAL|STRING]]) : INTEGER
    Parameter blob : table handle,field number (or)
    table handle,field identifier
    file : path of the file, where the content shall be copied to
    array : an array reference
    Return error code
    0 = successfully transmitted
    See also:
    linkblob() embedblob() blobsize()
    Description CopyBlob() can be used with embedded BLOBs only.

    If file is 'con', the BLOB is copied to the standard output channel.

    In case you pass an array reference instead of a file name you should keep in mind to dimension that array to the correct size (see BlobSize()) before. Otherwise you might lose data!
