This provides a very nice way to easily work on many files. You can even drag and drop a folder with select SQL files into a new Run SQL Scripts window, and a new tab for each file is opened.
- The Call (CALL) and Call Bound Procedure (CALLPRC) commands now allow expressions to be passed as parameters and allow you to specify type and length for each parameter.

Integrated File System Exit Points
Two new exit points are supplied in this release: QIBM_QP0L_OBJ_CLOSE and QIBM_QP0L_OBJ_OPEN. A new file system attribute, 'Run exit program', controls whether the exit programs registered to these exit points will run when a file system object is opened or closed. An exit program can perform application-specific processing when the object is opened or closed, such as verification, conversion, or removal of temporary objects. This support is enabled for the root, QOpenSys, user-defined, and QDLS file systems. More information can be found in the IBM i Documentation for these exit points:
- New opcode SND-MSG allows you to send an informational or escape message
