You can usually interrupt a batch file by pressing Ctrl-C or Ctrl-Break. Whether and when these keystrokes are recognized will depend on whether TCC or an application program is running, how the application, if any, was written, whether BREAK is ON or OFF, and whether the ON BREAK command is in use.
If TCC detects a Ctrl-C or Ctrl-Break when ON BREAK is not in use, it displays a prompt, for example:
Cancel batch job C:\CHARGE.BTM ? (Y/N/A) :
Enter N to continue, Y to terminate the current batch file and continue with any batch file which called it, or A to end all batch file processing regardless of the batch file nesting level. Answering Y is similar to the QUIT command; answering A is similar to the CANCEL command.
