IF in Scol¶

if <condition> then <instructions> else <instructions>

else is imperative.

More complicated :

if (((condition1) && (condition2)) || (condition3)) then
(
    instructions
)
else if (condition4) then
(
    instructions
)
else
(
    instructions
)

For a simple condition, like x < 5, the () is not imperative but recommended. For others cases, ( ) are needed.

Be careful, if <condition> then <instructions> else <instructions> is one instruction ! There is only a semicolon at the end of the last instruction of else block.

Example :

fun main ()=
    _showconsole;

    srand time;
    let ((rand&255)*100)>>8 -> x in    // randomized value
    if (x < 10) then
        _fooS "x is small"    // no semicolon !
    else if (x > 90) then
        _fooS "x is big"    // no semicolon !
    else
        _fooS "x is medium";    // semicolon !
    0;;

other example :

fun main ()=
    _showconsole;

    srand time;
    let ((rand&255)*100)>>8 -> x in    // randomized value
    let mod x 2 -> m in        // modulo x by 2
    if m == 0 then
    (
        _fooS strcat "x = " itoa x;
        _fooS strcat "x is even";
    )    // no semicolon !
    else
    (
        _fooS strcat "x = " itoa x;
        _fooS strcat "x is uneven";
    );    // semicolon !
    0;;
