Re: New parameter needed for a subprocedure

I think I understand what you want. Here's my suggestion.

In the prototype and interface, add the new parm and make it the last
parm. Use options(*Nopass) on the keyword of this new parm.


D SomePRC PR
D Parm1
D pNewParm 1 Options(*NOPASS)

D SomePRC PI
D Parm1
D pNewParm 1 Options(*NOPASS)

D NewParm S

/Free

NewParm = *Blanks;
If %Parms() >= 2;
NewParm = pNewParm;
EndIf;

/End-Free



Then you can change only the program(s) that need to pass that new parm.
All others remain as is.

A new parameter is needed by one of the callers of an exported sub

procedure.

Is there any harm in doing this :

Initialize the value of the new parameter in the exported sub procedure.

Add a new exported subprocedure GetNewParameter that returns

NewParameter.

The caller that needs the parameter continues to call the original
subprocedure as before and then calls GetNewParameter.

Other callers remain unchanged.

Does this make sense or is this just being lazy and are there any
risks of it going wrong?

Thanks
