PRG
Stops program execution. May be used to wait
for an input, for example.
STOS

STOS d
\
Stores all stack levels in a set of 4 or 8 registers,
starting at destination d.
STO+
d
\
Executes the specified operation on the content
of address d and stores the result into said ad-
dress.
E.g. STO12 subtracts x from r12 like the se-
quence 12   12 does, but
without touching the stack at all.
