MX_AUTOPARENT now supports an option to return the current auto parent. New syntax:
xcall MX_AUTOPARENT, newctlid {,oldctlid}
To retrieve the current setting without changing it, specify a literal null string for newctlid, e.g.
xcall MX_AUTOPARENT, "", oldctlid
In the ATE environment, the feature requires that both the server and client be at least at edit 1374. Otherwise, the oldctlid will be returned as -99.
