AbleScript

Functios

Functios in AbleScript can be defined using functio keyword, identifier, parentheses (that can optionally contain arguments) and functio body.

functio sayhello ()
{
   /*hello!*/ print;
}

Functio calls are statements, so they do not return any value. Luckily, all arguments are passed by reference, so you save return value by mutating them.

functio sum (aa, bb, return)
{
   aa + bb =: return;
}

return dim;
sum (3, 9);

See, how you do not have to pass the variable as an argument if variable already exists in the scope.

Eval

If you want to evaluate a value of code, simply call it:

num dim 4 + 2;
num + /*print*/ ();

Functio chains

Using + and * operators, functions in AbleScript can be "chained"

Chain kinds

• +: Equal - all arguments for chain are equally devided between left and right hand-side functions
• *: By arity - all arguments are distributed for every functio in chain by its arity

functio PrintA (arg)
{ /*A: */ + arg print; }

functio PrintB (arg)
{ /*B: */ + arg print; }

PrintA * PrintB (4, 2);

Output:

A: 4
B: 2
