These change much less from version to version: identical in MS-DOS 6.20/1/2 for example." Even if you're referring only to the "syscalls" interface of the DOS module (int 21h), they did change a lot between v1, v2, v3, and some for v4. The internal layout and structures of the DOS module also changed a lot over time. So this is wrong. Or did you mean "identical in v6.20 / v6.21 / v6.22"? That may well be correct, albeit not very relevant. | |
