The text outputting is kinda cringe but I couldn't think of another way. Outputs "BRING BACK THE OLD SANDBOX" until it hits a character that's not R.

Python:

print(''.join('BRING BACK THE OLD SANDBOX'if i=='R'else''for i in input()))

BASE:

ASSIGN i TO USER
WHILE TRUE:
  IF i IS R IF YES THEN
    PRINT BRING BACK THE OLD SANDBOX
