EDXOV allows you to specify a pair's starting position for the next session. You may assign their positions generally.
In two section crossovers, the afternoon N-S become E-W at the same table in the same section and afternoon E-W become N-S in the other section at the same table.
In a three section crossover, N-S become E-W at the same table and E-W become N-S in the next higher section at the same table. Pressing the F9 key will save your global crossover and allow you to edit specific crossovers within each section.
To indicate a single session pair, type "99" for next session assignment. After finishing each section, ACBLscore will inform you of duplicate table assignments.
To see the next session assignments for all sections of an event, use SHXOV.
See XOV syntax for examples.
