I am not really doing a traceroute, just pinging some important points
along the way.  And I want more data than tracert gives.

This is pretty cool.  I wasn't even thinking this simple, but I can make
that work, I think!

Echo with a . prints a . so I am still looking for a way to print a blank
line.

I figured out how to replace chars like this, but I wanted to delete the
15th character in line 12 or remove the 5 spaces at the begining of line 4.

basically I repeat this:
ping -n 1 %ROUTER_INTERNAL_INTERFACE% > %temp%\zzxyy003.tmp
edlin %temp%\zzxyy003.tmp < %temp%\zzxyy001.tmp > nul
fc /w %temp%\zzxyy002.tmp %temp%\zzxyy003.tmp > nul
IF ERRORLEVEL 1 echo INTERNAL ROUTER INTERFACE (%
ROUTER_INTERNAL_INTERFACE%) IS DOWN
IF NOT ERRORLEVEL 1 echo INTERNAL ROUTER INTERFACE (%
ROUTER_INTERNAL_INTERFACE%) IS UP

nine times and just use different varables.  There must be a way for me to
write this once and have it run 9 times with the correct information?
