Replacing Characters in String

Try this

setlocal set string=cat rat mat fatset string=%string:t=p%

string windows batch-file character

You've got the = sign in the wrong place. Try:

setlocal enabledelayedexpansionset /P MY_TEXT=ENTER TEXT:SET T2P=Pset NEW_TEXT=%MY_TEXT:T=!T2P!%MSG * %NEW_TEXT%

You can also do the expansion the other way round, i.e.

set NEW_TEXT=!MY_TEXT:T=%T2P%!

You could use 'sed' like this:

echo "cat rat mat fat" | sed 's/t/p/g'  # outputs "cap rap map fap"
