Hi Scott -

Given this plist ...

> 0059.00 c                   parm                    peUserDscInfo
> 0060.00 c                   parm                    peDevDscInfo
> 0061.00 c                   parm                    peCnnDscInfo
> 0062.00 c                   parm                    peEnvOpt
> 0063.00 c                   parm                    peEnvOptLen
> 0064.00 c                   parm                    peAllowConn
> 0065.00 c                   parm                    peAutoSignOn

Why have this ...

> 0069.00 c                   eval      p_CnnDscInfo = %addr(peCnnDscInfo)

> 0044.00  ** Connection Description Info structure
> 0045.00 D p_CnnDscInfo    S               *   inz(*NULL)
> 0046.00 D dsCnnDscInfo    DS                  based(p_CnnDscInfo)

and not ...

0044.00  ** Connection Description Info structure
0046.00 D peCnnDscInfo   DS

with the appropriate subfields?  Unless I'm missing something (quite 
possible) I don't see the need for the pointer or pointer-based data structure.
