rem U2_EXUCN.BAT accepts a single parameter: an archive file. It
rem decompresses all files (including hidden ones, etc.) of this archive
rem completely into the current directory. If nothing goes wrong, the files
rem U$~CHK1 and U$~CHK2 are created by this batch file. UC tests for the
rem presence of those files.
rem Notice that UCN files are handled just like UC2 files. The purpose is
rem to allow "conversion" from UCN to UC2 of files. The conversion may
rem include several operations you want to perform. (e.g. adding banner,
rem virus scanning)
rem 1. UC
rem *** UC ***
rem *** WARNING: Only revision 0 (newest) files are extracted ***
rem Add file to archive
echo check > u$$chk1
uc a %1 u$$chk1

rem Expand archive
uc xsf %1
ren u$$chk1 u$~chk1
rem Test for correct expansion

if not exist u$~chk1 goto error

rem Call 'extra' file, allowing e.g. addition of banners
command /cu2_xtra
rem Create second check file to notify complete success to UC
