-==__EXEC==
-Allows you to assign values to variables. These variables can then be used to in other calculations, or output via the __EVAL macro.
-<code>__EXEC (_x = .345);
-__EXEC (_y = _y + 1);
-__EXEC (_str = format["name: %1",_name])</code>
-__EXEC terminates at the first closed parenthesis "''')'''" it encounters, so expressions like the following will cause an error:
-<code>__EXEC (_val = (_arr select 0)*10); // ILLEGAL!</code>
-==__EVAL==
-With this macro expressions can be evaluated, including previously assigned internal variables.
-<code>y = __EVAL (_y);
-text = __EVAL (_str1 + _str2);</code>
-Unlike the __EXEC command, __EVAL ''can'' contain other parentheses, making more complex, and even conditional operations possible:
-<code>x = __EVAL (if (_idx>5) then {0} else {.5});</code>
-Be aware though, that if these evaluations are used in a mission's description.ext, that at that point the mission information is not available yet (i.e. the mission objects have not been created yet). (''At least in VBS2 this is the case.'')
