ASK [question]

* ASK prompts the user with a question requiring a Yes or No
  answer. If the first letter of the users response is "Y", ASK
  returns code WARN. Responding "E" returns ERROR, "F" returns
  FAIL. Any other letter will result in return code OK.
  The question can include ASCII characters as well as control
  codes as per the  ECHO  command.

eg.     ask "Do you want commands copied to ram? "
        if warn
               copy c: ram:
        endif

Note: You can  redirect  the ANSWER to a file by redirecting the OUTPUT.
eg.     ask >ENV:CallIt        {The answer is written to CallIt}
