The FORMAT command

If you want to redirect the input for the FORMAT command, you should use one of the following techniques: 

 
  "type format.dat | format C:"

or 

 
  " program | format C:"

format.dat must be an ASCII file containing the user input for the FORMAT program; program can be any OS/2 program that writes the necessary user input for the FORMAT program to STDOUT (for example a REXX program). You can't use the ECHO command to pipe the input for the FORMAT command.
