RPG ILE Recursivity RNX8888

Hi,
First I must say that I often search and read these forums. Thank you all
for your help.

Here's something I would appreciate your help with.

>From what I've been reading... RPG ILE does not support recursivity.
That is an RPG program calling itself either directly or indirectly.

And that is true because I have a situation where I tried it and I received
the RNX888 RPGPGM1 was called recursively.

Where I get confused is another recursivity test that I have done and IT
WORKED!

I wrote a program with ACTGRP(*NEW)
Here's the code

H ACTGRP(*NEW)
D @Var1ds         DS
D  @Var1arr                     10a   dim(10)
D @Var1Ptr        s               *   Inz(%Addr(@Var1ds))
D @Var2           s                   Based(@Var2Ptr) Like(@Var1ds)
D @Var2Ptr        s               *
C     *Entry        Plist
C                   Parm                    @Var2Ptr
C                   If        %Parms = 0
C                   Eval      @Var1Arr(2)='Hello'
C                   Call      'A1'
C                   Parm                    @Var1Ptr
C                   Else
C                   Eval      @Var1ds = @Var2
C                   EndIf
C                   Eval      *InLr = *ON
C                   Return

This is working.

Can someone tell me why recursivity some times works and some times it
doesn't?
What are the conditions that stops it from working and how can I get around
them?
