DECAMSET takes Unicode data that was compressed using the CAMSET function, uncompresses it, and returns an uncompressed Unicode character string as the result.

Although you can call the function directly, DECAMSET is normally used with algorithmic compression (ALC) to uncompress table columns previously compressed with CAMSET.
