Not good without some work, said docs explicitly state this:

On DOS32 or WIN32, system_exec() will only run .exe and .com programs. To run
.bat files, or built-in DOS commands, you need system(). Some commands, such as
DEL, are not programs, they are actually built-in to the command interpreter.

If you have an external command called dir.com, system_exec() will work for you.
What you can do for internal commands is this

?system_exec("command.com /c dir *.txt",2)

command.com is an external program, and the /C switch instructs it to execute
the remainder of string and return status code. command.com will be done in a
secondary DOS shell.
Under Windows, use cmd.exe rather than command.com if it is available.
