While both ways are currently equivalent and the string constant is created, we recommend the use of curled braces for code only, as this makes scripts easier to read - moreover future versions of scripting language may precompile code enclosed in curled braces.

Since Armed Assault the convention to use quotation marks for Strings and curly braces for Code has been formalised. Exceptions, however, do exist. For example onMapSingleClick and onDoubleClick.
When scripting, 'abc' or "abc" generally indicates a String data type, and brackets { } indicate Code data type.

In Operation Flashpoint, many language constructs (including forEach) use the concept of "code strings". Code is passed as a string to them and they interpret it as code if they wish. Since version 1.85, code is also accepted.

// Operation Flashpoint / Armed Assault only! "_x setDammage 1" forEach _units; // from Operation Flashpoint v1.85+ up to Arma 3 { _x setDamage 1 } forEach _units;


Code Commands

Code commands are any commands from the scripting language expecting a coded statement string as one of their parameters. Earlier engines accepted code as such when it was provided as a String using quotation marks, or using braces. Since Armed Assault the engine specifically requires braces. Thus, because the way the engine determines whether it is dealing with code has changed, this list is presented here.
