Question #1 : How MWC's msh is discovering who called it ?
 (desktop, or other...) it is in the local shell variable 'calledfrom'.
An other shell is able to tell the list of all parents programs...
The base page does not contain any backward pointer, so what is it ?

Question #2 : I read again the dev kit doc on shell_p, the posting
by A.Pratt about it, and I still wonder : what is it ?
I would infer it is a pointer to a string telling the file name of a shell...
I am right ?
What would be the use otherwise ?

Regards,

Jean-Pierre H. Dumas
