Language Reference

RETURN Statement

returns to caller

RETURN <(operand)>;

where operand is the value of the function returned. Use operand only in function modules.

The RETURN statement causes IML to return to the calling point in a program. If a LINK statement has been issued, IML returns to the statement following the LINK. If no LINK statement was issued, the RETURN statement exits a module. If not in a module, execution is stopped (as with a STOP statement), and IML looks for more statements to parse.

The RETURN statement with an operand is used in function modules that return a value. The operand can be a variable name or an expression. It is evaluated, and the value is returned.

See the description of the LINK statement. Also, see Chapter 5, "Programming Statements," for details.

If you use a LINK statement, you need a RETURN statement at the place where you want to go back to the statement after LINK.

If you are writing a function, use a RETURN to return the value of the function. An example is shown below.

   start sum1(a,b);
      sum=a+b;
      return(sum);
   finish;
