- +<sup>*</sup> When EXEC detects an error in an entered command, it will display a "?" and possibly an error message.  Pressing **Ctrl-H** will retype at the EXEC prompt the command text up to the location where EXEC detected the error, allowing the user to correct just the erroneous portion and reenter.
  
 ===== Subcommands ===== ===== Subcommands =====
  
 +To enter subcommands, type a comma ('','') at the end of the command line before pressing **Enter**. EXEC will respond with the subcommand prompt (default ''@@''). Enter a subcommand and press **Enter**, repeating for as many subcommands as you wish to specify. Press **Enter** on a blank line to end subcommand input and EXEC will process the command with the specified subcommands.
