After successfully loading ROMA, the instructions C
, D
, I
, L
,
M
, V
, and X
take on new semantics.
C
pushes 100 onto the stack.D
pushes 500 onto the stack.I
pushes 1 onto the stack.L
pushes 50 onto the stack.M
pushes 1000 onto the stack.V
pushes 5 onto the stack.X
pushes 10 onto the stack.
Note that these are just digits, you still have to do the arithmetic
yourself. Executing MCMLXXXIV
will not leave 1984 on the stack. But
executing MCM\-+LXXX+++IV\-++
should.
