Batch

For the grouping of object properties, see Batching.

The batch is the precursor of the stack. It was obsoleted with the Sixth Edition rules changes.

From the The Pocket Players' Guide for Magic: The Gathering - Fourth Edition (1995)

Batch (Obsolete)

A series of non-interrupt fast effects that build on one another as players respond to each other's spells. Batches are resolved by first-in, last-out for all effects. Any damage done to creatures or players isn't applied until the end of the batch, but creatures that are destroyed through means other than damage are sent to the graveyard immediately and regeneration and/or death effects are checked when this occurs.

Because damage waited until all spells in the batch resolved, this meant that if you cast Giant Growth on your creature, your opponent couldn't Lightning Bolt it out from under you. Another way this differs from the stack system given the interrupt type is that a color changer like Deathlace could pre-emptively counter a second copy of Terror, as opposed to something like Prismatic Boon, which as an instant could only protect against the first.
