For System 36 users that have thoroughly researched the move to the AS/400 and decided they want nothing to do with it, Software Ireland Ltd is offering the freedom of a jump to open systems with its Unibol product, which provides a System 36-compatible development and execution environment under Unix, and has just launched Release 4.0 of the product. The new release adds support for SSP 6.0 Call/Parm, so that RPG II programs can call other RPG II programs. It also includes initial versions of Unibol RPG400 and Unibol Cobol. And a new shared data facility means that Unix applications can open, close, create and update new Unibol data files; and read, write and update records. A library of C functions can be called by RPG II; no price.
