Euler procedures can return a list (Euler's only data structure), ths is used here to return three values from the getMV procedure.
<br>
Procedures are defined by enclosing their text between ` and '. They can then be assigning to a variable for later use.
<br>
Lists are constructed by placing the values between ( and ). Once assigned to a variable, the list can be subscripted to access the individual elements (which can themselves be lists).

new mv; new getMV;

mv <- getMV( 3 );
out mv[ 1 ];
out mv[ 2 ];
out mv[ 3 ]
end $
