For my two-pennies worth, if your line reads as you have typed it here,
you are bound to run into trouble.  \ is the C string escape char, so the 
line to the program looks like
"C:COMMON.COM", ie the directory information is lost.  (\C goes to C).
If the current directory for C: does not contain a COMMAND.COM, then
you should get some failure.  Better to get the directory information
from the environment variable, COMSPEC.
