WMB 6.
I have a procedure that takes in a reference to InputRoot and Environment.
CREATE PROCEDURE logMessage(In InputRoot Reference, In Environment Reference)
Is there any benefit (resource saving, etc) to passing it a reference versus InputRoot and Environment directly?
Declare InRef Reference To InputRoot;
Declare EnvRef Reference To Environment;
Call logMessage(InRef, EnvRef);
vs.
Call logMessage(InputRoot, Environment);
Thanks!!!!!! |

One works and the other doesn't.

??? 
Care to elaborate some? From my experience both work however there are some marked differences that can be aleviated by astute coding... or is this only the case in V6?

Both do work. The examples in the WMB6 documentation usually show the pattern:
Call logMessage(InputRoot, Environment);
However, we would like to know if WMB is making "copies" of InputRoot and Environment everytime we do it this way. I couldn't see any documenation that clarifies this.
Thanks!!!!!! |

No. It is not making copies because if you modify Environment, it is still modified after return.
