This is not supposed to be a bug on a ST. The only possibility it has is to make
a system call which is handled by the shell ( like U*IX system() ) by calling
a routine who's pointer is in the system variables ( I don't know which; sorry )

A possibility you do have is when moria does a shell escape ( or some other programs as well ) is to setenv SHELL to the name of the shell; I set it to the name
of a small program ( source on request ) which just reads a line and executes it
by calling system on this line.
