| COPY ASCII mode support |
| "notify pending command" support (INT 2F,AX=AE00) |

| 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) |
| compression of NLS strings and rmod core (lz4?) |
| dynamic resizing of environment space |
