Are you using 4DOS as a COMMAND.COM replacement, or any other replacement 
for COMMAND.COM??  If not, are you using the correct COMMAND.COM for 5.0?  
This is a known problem with 4DOS, as the DOS programs use a part of 
COMMAND.COM for processing of help and extended errors.  If you don't use 
MS-DOS 5.0 COMMAND.COM, you get exactly what you are describing.
