$save in Icarus Verilog

[Kenneth Brun Nielsen]

Can I save the state of a simulation using Icarus Verilog simulator?

I found the $save command in Google, but it doen't seem to work in
Icarus (vvp).
"
$save1: This task not defined by any modules. I cannot compile it.
ta_test: Program not runnable, 1 errors.
"

Any alternatives in Icarus?

Best regards,
Kenneth
