Help me understand what is happening with my NGSPICE coding..

[sr13579]

The thing is, I am confused with rawfile and .print card (spice.out file).
There are like 3 options for rawfile generation: NONE,COMPACT and ACCURATE. While I am using NONE with the .print card the result is going inside a .out file without generating a rawfile. But when I am using ACCURATE or COMPACT the print card is ignored and showing some no listing warning. The rawfile is generated but the code is ignoring print card which means I am not getting any analytical result. How to fix this problem?(The code is:
Voltage divider
r1 1 2 10k
r2 2 3 5k
r3 3 4 4k
r4 4 0 3k
v 1 0 dc 4
.dc v 4 4 1
.print dc v(1,2) v(2,3) v(3,4) v(4)
.op
.end

hi

I use LTspice but the code should work.

This is all you need:
<-----I had to put a blank line here for the code to work.
r1 1 2 10k
r2 2 3 5k
r3 3 4 4k
r4 4 0 3k
v1 1 0 dc 4 <---I renamed the voltage source for clairity
;.dc v1 4 4 1 <---don't need this because it defines a DC sweep
.op
;.print dc v(1,2) v(2,3) v(3,4) v(4) <--don't need this because .op prints out all voltage and currents.

Results from LTspice:

--- Operating Point ---
V(1): 4 voltage
V(2): 2.18182 voltage
V(3): 1.27273 voltage
V(4): 0.545455 voltage
I(R4): 0.000181818 device_current
I(R3): 0.000181818 device_current
I(R2): 0.000181818 device_current
I(R1): 0.000181818 device_current
I(V1): -0.000181818 device_current

See that is what I was talking about. It won't generate a printed file .This is what is painful.
