[Jprogramming] EVM

[bill lam]

First of all because of change in syntax,  you have to change the line

to
setup m

and then it works like this
   '*: 4' EVM
16
   hist ''

 Queue         Stack               Rule

 +---------+   +------+----+---+   +-----+
 |mark *: 4|   |      |    |   |   |     |
 +---------+   +------+----+---+   +-----+
 |mark *:  |   | 4    |    |   |   |     |
 +---------+   +------+----+---+   +-----+
 |mark     |   | *:   | 4  |   |   |     |
