What I will say, is that in SuperSpice, there is docked signal list tab that
you can click on to display, for example, Vds and Vdsat together so that you
can check immediately, over process corners, whether the device is operating
in the correct region over DC or transient sweeps.

My grammar was poor. There's an undocumented .PRINT in _PSpice_, that
simply requires making a symbol (*) that spits out a .PRINT statement.
AFAIK there is no such equivalent in LTspice, though one might try
using the LTspice vernacular "Spice directive", .PRINT...
(*) An alternate way is discussed in...

I just remembered, I have a Berkeley Spice3F3 manual which might offer
some hints on finding hidden features in LTspice. I'll post a link
tomorrow.
As for a .OUT file equivalent, I haven't found any such creature.

Jim,
I used .out files to look at effective transistor widths and lengths as well
as the operating points. I miss this in LTSPICE. Is there a way to get these.
Also, how could I get the probe with a printer t
that you came up with?

LTspice should have a .PRINT statement like PSpice.
Undocumented now, but it's still there... I just made a symbol for it,
somewhat like a probe symbol, but with a printer on top.
I stick it on a node where I want a numeric listing, and the listing
appears in the .OUT file, ala Berkeley.
I use such listings to do post-processing in Excel, or create PWL
sources, or in IBIS modeling.
The output data points are equal-spaced ("Print Step" in the .TRAN
settings). In LTspice (there is no .OUT file), I understand that you
can get an unevenly-spaced list, requiring using an executable by
Helmut Sennewald to extrapolate to evenly spaced.
I have an executable (Aaron wrote it for me) that takes this evenly
spaced data and optimizes it for least amount of points needed for PWL
or IBIS models (IBIS has a 100 point limitation on most descriptors, a
real PITA, so you have to be creative :-)

Probably why I never saw them. When I last used Berkeley Spice
(~1980) I used the .OUT file to drive a tractor printer, outputting a
numerical list of voltage versus time and *'s marking a rough waveform

Certainly, with LTspice. I tend to be a stickler and follow Spice
standard conventions, avoiding lots of confusion...
.CIR, circuit file, ready for simulation
.NET, netlist file, components, but no simulation information
.OUT, output file, bias points, etc.; sometimes numerical "listing"
of output data in Berkeley Spice format (PSpice, HSpice,
SmartSpice do this, LTspice does not :-(
.DAT, output data for viewing in a post-processor
.RAW, LTspice of conventional Spice .DAT
.LIB, the most usual way of conveying models
.MOD, .SUB, unconventional, but also used for models
.INC, (.INCLUDE), the garbage way to pass libraries, takes much
space since all devices listed in library are loaded.
.LIB, loads only the devices in your schematic
PSpice has other extensions, as well, for passing messages and error
notifications.
