final DEMPOV.exe output is interesting,
4 parameters 0 1 1 0, using default bias,
might be correct usage.

 file gce.tga
  1442401 pixels were written to the file.
 For converted data points:
      MinValue =      0.000 MaxValue =  65535.000

but do the heights align, yet to be tested.

0 0 15 0,
used in previous renders, heights aligned.
with a hefty block underneath.

need more test renders.
all i got so far.

Niagra county,
only 6,
not normalized,
bias of 0, aligned heights better than default bias.
but Gasport was way off

fine tuned ...
path %PATH%;c:\ftp\dempov\bin
DEMPOV akron.dem akron.tga 0 0 4.5 0 0
DEMPOV barker.dem barker.tga 0 0 5 0 0
DEMPOV gasport.dem gasport.tga 0 0 16 0 0
DEMPOV lyndonville.dem lyndonville.tga 0 0 5 0 0
DEMPOV medina.dem medina.tga 0 0 4.6 0 0
DEMPOV wolcottsville.dem wolcottsville.tga 0 0 4.6 0 0

got enough options,
just depends on the data you have, apparently.

Shasta county and Mount Shasta were 0 0 15 0

and for the user friendly stuff, add this,

alias deminit {
  %parameters = 0 0 15 0
  %WorkingDir = c:\ftp\dempov\bin
  %proj = untitled
  ; if (!init) program uses defaults
}
menu status {
  -
  DEM Initialize: deminit
}

added project title, which is set with a filename if you dont.
title*.bat files makes more sense.

thanks if it has DEM files. would be cool.

probably should have waited another a week to post, it's never done.
with bulletproof defaults, it wont error.
reading the program answers all questions.

post any changes to main.c or dems*.mrc -
if two heads aren't better than one, everything is doomed for sure.

Current issue in main.c is a 2-4 degree rotated image, for some DEMs.
