This paper gives an array-based practical encoder for the lossless data compression algorithm known as Compression by Substring Enumeration (CSE). The encoder makes use of the relation between CSE and the Burrows-Wheeler transform. We also modify the decoding algorithm to accommodate to the proposed encoder. Thanks to the proposed encoder and decoder, we can apply CSE to long data of more than tens of megabytes. We show compression results obtained when we perform experiments on such long data. The results empirically validate theoretical predictions on CSE.
