5.2.10 return
Syntax:
return ( expression_list );
return ();
Type:
- any
Purpose:
- returns the result(s) of a procedure and can only be used inside a
procedure. Note, that the brackets are required even if no return value
is given.
Example:
| proc p2
{
int i,j;
for(i=1;i<=10;i++)
{
j=j+i;
}
return(j);
}
// can also return an expression list, i.e., more than one value
proc tworeturn ()
{ return (1,2); }
int i,j = tworeturn();
// return type may even depend on the input
proc type_return (int i)
{
if (i > 0) {return (i);}
else {return (list(i));}
}
// then we need def type (or list) to collect value
def t1 = type_return(1);
def t2 = type_return(-1);
