INT 2E - Execute Command Using Base Level Command Interpreter
(Undocumented DOS 2.0+)
DS:SI = pointer to command string to be executed
returns nothing ???
- causes the base level COMMAND.COM to execute a command as if it
were typed from the keyboard
- the transient portion of COMMAND.COM must be loaded if not resident
- first byte of the string contains the string length, inclusive
- command string must be terminated with a CR
- all registers including SS & SP are destroyed; SS & SP should be
preserved in your own code segment
- can be used to modify parents environment with SET command
- incompatible under some software multitasking systems
- before returning to the parent program this interrupt will
attempt to execute the "current" batch file (if the parent or
any ancestors were invoked from a batch file. This can cause
remaining lines in a batch file to execute before the parent
program finishes and fragment memory
