## 13.7 Looping Support

Two routines are supplied which affect the behavior of loops within Data Explorer. Loops are typically initiated with the ForEachMember or ForEachN modules. From within a user-written module, you could terminate a loop by calling `DXLoopDone`.

`void DXLoopDone()` | Terminates a loop. See DXLoopDone.
`int DXLoopFirst()` | Indicates whether it is the first time through a loop. See DXLoopFirst.
