All variables in RECOL 26 must start with the $ symbol and must be declared before use.

First, a variable must have a data type:


$variable1 :: string;

Then a value can be assigned:


$variable1 := "hello";


string
int
bool
char


$var1 :: int;
$var1 := 67;

$var2 :: int;
$var2 := 50;

$sum :: int;
$sum := $var1 + $var2;

All data must be stored in variables before output.


$string1 :: string;
$string1 := "I am sigma";
display($string1);

Direct output of literals is not allowed:


display("hello");  // NOT ALLOWED


$input1 :: string;
accept($input1);
