Re: command_line() - convert a sequence to an atom value?

CK presents one method or you can use something like this
which is ultra fast,

address = allocate(256) -- 'warning' only 256 bytes can be used
mem_set(address, 0, 256)

poke your value staring at 'address' location
and then you can peek the value from 'address' later
when its needed again.

if you have some code, I could help you modify it some to work like this.
