It is true that one can go in for this type of statement, but what I would like to add
is that the statement
ReturnVal := CALL XYZ(a,b,c)
will be more useful when one declares new variables inside the procedures ( that can be
INTEGERS, CHAR's , Structures etc.) and would like to be available at the calling point,
but ofcourse the OUT statement will work over there, but when a RETURN is used one can
get back the value into a different variable altogether at the calling point!

Hello,
In that case you can also write in a PROCEDURE CALL SDL symbol:
XYZ(a,b,c,RetrunVal)
(but this is less easy to read than using a TASK).
