12,7 → 12,6
pipes redirections
basic BAT support (without workflow controls, FOR loops etc)
COMSPEC self-setting does not work under MS-DOS 5/6 (no exepath in env block)
AT SOME LATER TIME:
34,6 → 33,7
INT 2F,AX=5500 support
stdout redirection should not create the output file if command fails
COMSPEC self-setting does not work under MS-DOS 5/6 (no exepath in env block)
when execing an external command make sure to sync local environment (or run the program with a custom environment pointer?)
