gtpm1m1xTPF V4R1 Migration Guide: 3.1 to 4.1

Internal Event Facility

In the TPF 4.1 system, you do not need to consider the size of the internal event facility table because it is dynamic. The TPF 4.1 system uses a hashing technique to locate entries and changes the size of the table as needed. When data in a block is passed by the $CONBC and $DISBC macros, the data is passed, not the actual block. Therefore, data in a core block cannot contain pointers to data in that same core block.

See TPF System Macros for more information about the $CONBC and $DISBC macros.
