+# COMPLEXCONDITION
+
+An object that combines two conditions ([`CONDITION`](CONDITION.md) or nested `COMPLEXCONDITION`) with a logical `AND` or `OR` operator. Configured by three fields in the script and invoked similarly to a `CONDITION`.
+
+## Fields
+
+### CONDITION1
+
+```
+STRING CONDITION1
+```
+
+The name of the variable holding the left-hand sub-condition. The referenced variable should be of type [`CONDITION`](CONDITION.md) or `COMPLEXCONDITION` — in either case it is evaluated recursively.
+
+### CONDITION2
+
+```
+STRING CONDITION2
+```
+
+The name of the variable holding the right-hand sub-condition; the rules are identical to those of `CONDITION1`.
+
+### OPERATOR
+
+```
+STRING OPERATOR
+```
+
+The logical operator joining the two sub-conditions. Defaults to `AND`. Accepted values:
+
+| Value | Meaning |
+|---|---|
+| `AND` | conjunction — the whole is true when both sub-conditions are true |
+| `OR` | disjunction — the whole is true when at least one sub-condition is true |
+
+## Methods
+
+### BREAK
+
+```
+void BREAK([BOOL emitSignals])
+```
+
+Evaluates the compound condition. If the result is `TRUE`, aborts the entire current call tree (the same effect as [`@BREAK`](../engine/scripts.md#jump-operators)).
+
+**Parameters**
+
+- `emitSignals` — (optional) if `TRUE`, [`ONRUNTIMESUCCESS`](#onruntimesuccess)/[`ONRUNTIMEFAILED`](#onruntimefailed) signals are fired by both this object and each sub-condition. Defaults to `FALSE`.
+
+**Examples**
+
+```
+COC_END^BREAK(TRUE);
+CCONDISATPOS^BREAK(TRUE);
+```
+
+### CHECK
+
+```
+BOOL CHECK([BOOL emitSignals])
+```
+
+Evaluates the compound condition and returns the result.
+
+**Parameters**
+
+- `emitSignals` — (optional) same as for [`BREAK`](#break).
+
+**Returns**: [`BOOL`](BOOL.md) — the combined result.
+
+**Examples**
+
+```
+CCONDTESTEND^CHECK(TRUE);
+```
+
+### ONE_BREAK
+
+```
+void ONE_BREAK([BOOL emitSignals])
+```
+
+Evaluates the compound condition. If the result is `TRUE`, aborts only the current procedure (the same effect as [`@ONEBREAK`](../engine/scripts.md#jump-operators)).
+
+**Parameters**
+
+- `emitSignals` — (optional) same as for [`BREAK`](#break).
+
+**Examples**
+
+```
+COC_END^ONE_BREAK(TRUE);
+CCONDISATPOS^ONE_BREAK(TRUE);
+```
+
+## Signals
+
+### ONRUNTIMESUCCESS
+
+Fired when the compound condition evaluated to `TRUE` and `emitSignals` was `TRUE`.
+
+### ONRUNTIMEFAILED
+
+Fired when the compound condition evaluated to `FALSE` and `emitSignals` was `TRUE`.
