I want to be able to concat a new ECHO message to a prior ECHO message, something like this:
Command:
ECHO PROCESSING...
REM some process here
ECHO DONE
Result:
PROCESSING...
DONE
What I want as a result is this
PROCESSING...DONE
I will first echo the "PROCESSING..." message, and then after my process is done, I would like to be able to append the "DONE" message at the end.
