Finally remembering what I forget about DOS batch files, the
example of execution with the input images to be sample%d.tga in
a .bat file gets the error message, can't find sampled.tga. But
of course it works from the command line. 

	The problem is that batch files use % also. To make it work from
a batch file the format is 2 % as in sample%%d.tga and then it
works from a batch file. 

	Get away from DOS for a few years and you forget everything. :(

Hmmmm, I thought I must have tried that though. I ended up with a
"sample%02d.tga" (0 being the padded digit[?] and 2 being a double digit
set of image frames for example) and all works fine.
Here's my super simplistic batch:

@echo off
cd mpg_util\avi2mpg
cls
echo.
echo  Busy...
echo.
cmpeg -v0 -t0 -f2 ipb.ctl c:\povanim\create\%1d.tga %2.mpg
echo.
dir %2.mpg
cd \

And I just enter MPG IMAGES%02 ANIMATE on the command line replacing the
counted digits with %02 (example).
I'm going to check using the double percent as you said.
