Version 2.5 of dsread was released in January 2014. It reads datasets from a wide range of platforms including 32- and 64-bit Windows and 32- and 64-bit versions of most Unixes. Datasets compressed using CHAR or BINARY compression are handled correctly. Although written for Windows, it can be run under Wine on Linux.
