In the following example, the content of C (HR 00) is 8010, and COLL(81) is used
to copy the most recent entries from a 10-word stack (IR 001 to IR 010) to LR 20.

ER: The content of C is not BCD or 6655<C<8000.
When C≤6655, DBs and DBs+C are not in the same data area.
When C≥8000, the beginning and end of the stack are not in the same
data area or the value of the stack pointer exceeds the length of the
stack.
Indirectly addressed DM word is non-existent. (Content of ∗DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ: ON when the transferred data is zero; otherwise OFF.
