Block Syntax
if (expression) {
	block;
} else {
	block;
}

For example: 

 if (param[1] == 1) {
 	param[2] = 3
 } else {
 	param[2] = 5
 }

For a single variable or property assignment the ternary operator might be shorter: 

result = boolean_value ? if_true : if_false;

e.g. 

ground_sprite = (nearby_tile_type(0,0) == TILETYPE_DESERT) ? GROUNDSPRITE_DESERT : GROUNDSPRITE_NORMAL;
