How do I use this DOS compression program? Please advise, thanks - China DOS Union Forum

This software is not a compression program for executable files, but I heard that EXE files inside an ARC archive can be run without being extracted from the archive first. But I haven't tried it.
From the information below it, its usage is more or less similar to ARJ, RAR, and AIN
============
Usage: UHARC command archive

Commands:
~~~~~~~~~
a Create archive/Add files e Extract files to current dir
m Create archive/Move files x Extract files with full path
l List files in archive t Test files in archive

Switches:
~~~~~~~~~
ac Clear file archive attr ae Set attr exclusion mask
b Set max filebuffer size bpb bpb instead of % ratio
d Set display mode ed Store empty directories
idle Set idle process priority lg Log output to
m Set compression mode md Set dictionary size
mm MM-detection on/off o Set overwrite mode
pw Set password p Set path handling
r Recurse subdirectories t Set extract target dir
vm Set virtual memory usage y Assume yes on all queries
=================
If you want to compress DOS EXE and COM files, you can use PKLITE and DIET.
If you only want to compress EXE files, I recommend WWPACK and UPX. UPX can also compress EXE files for WINDOWS3X/9X/NT/2000.

I want to ask whether this software can compress DOS COM and EXE files? After compressing them, can they still be used normally? Thanks.
