Description

Description:
Adds given set of compiled instructions to the current stack and waits for it to finish and return, provides an option to pass arguments to the executed Code.
ⓘ
called code runs in the scope it is called, as if the code were copy-pasted there, (un)scheduled environment included.
⚠
This command accepts String (as well as Code) only in Operation Flashpoint. For later titles, see compile.
Groups:
Program Flow

Syntax

Syntax:
call code
Parameters:
code: Code - compiled instructions
Return Value:
Anything - The last value given in the function is returned. See the topic Function for more information.

Alternative Syntax

Syntax:
args call code
Parameters:
args: Anything - Arguments that are passed to the function in the _this variable
code: Code - compiled instructions
Return Value:
Anything - The last value given in the function is returned. See the topic Function for more information.

Examples

Example 1:
call { hint str 123; };
Example 2:
123 call { hint str _this; };
Example 3:
_sum = [1, 2] call { (_this select 0) + (_this select 1); }; hint str _sum; // displays 3
Example 4:
123 call compile "hint str _this;";
Example 5:
_result = 123 call compile preprocessFileLineNumbers "myFile.sqf";
