We already know that by replacing the "DEL" characters in COMMAND.COM with other characters, users can't use the DEL command.
Humbly asking, how to modify COMMAND.COM (using software like UltraEdit) to prevent users from terminating batch processing with CTRL+C? That is, which part or parts of COMMAND.COM need to be modified?

Modify the header or maybe the body of command.com. It's really sad that Ctrl+C terminates the batch processing.

Use 4DOS. It allows you to make the responses you specify for the CTRL-C or CTRL-Break key presses

It's of little significance!
Because the processing of CTRL+C is in the INT 23h interrupt, you can modify this interrupt to execute the user program;
Or more simply, SHELL=x:\abc\command.com, and the COMMAND.COM you modified will immediately become invalid!
