     To find the best compression level, I use next batch (for NDOS/4DOS)=
:

______________O\_/_________________________________\_/O______________
@echo off
if not "%1"=3D=3D"@" goto main
if not "%4"=3D=3D"" goto next

apack -x %2%3 %2.0
%0 @ %2 %3 1 0

:next
if "%4"=3D=3D"4" goto end
apack -x%4 %2%3 %2.%4
iff %@filesize[%2.%4] lt %@filesize[%2.%5] then
        del %2.%5>nul
        %0 @ %2 %3 %@eval[%4+1] %4
else
        del %2.%4>nul
        %0 @ %2 %3 %@eval[%4+1] %5
endiff

:main
if "%1"=3D=3D"" %0 *.com *.exe
for %%f in (%&) do call %0 @ %@name[%%f] .%@ext[%%f]

:end

How to run:

- to pack all files in current directory: "packall.btm *.*"
- to pack prog.exe and all .com files in current directory:
  "packall.btm prog.exe *.com"
- to pack c:\release\kernel.exe: "packall.btm c:\release\kernel.btm"

Packed files will be placed _in current directory_, with original name, a=
nd
numeric extension, which is equal to (best) method, which was used to pac=
k
this file.
