This feature can be used whenever it's necessary to control allocations to specific Units regardless of the position of the Unit to group allocated I/O words by device or circuit or to prepare for future changes to or additions of I/O Units for system design changes. Word Allocations When setting first words for slots, the first word must be set for slot 00 on the CPU Rack. The first word can then be set for any slot on any Rack for up to 63 other slots. Each first word set for a slot creates a group starting with that slot. Words are allocated starting from the specified word to the first slot in the group and continuing left to right allocating consecutive words to each Unit until the next group (i. e. , until the next Unit for which a first slot word is set). The next group can start on the same Rack or on a following Rack. 355 Allocating First Words to Slots and Reserving Words Example: Setting the First Words for Racks Section 8-3 In this example, a first slot word has been set in the middle of each Rack. For simplicity, only 16-bit Units have been used.
