Discrepancy between original DEBUG and DOS-debug #9

Closed ijean closed 1 year ago

Hi,

I found a discrepancy (possible bug) between original debug from MS-DOS 6.22 and the DOS-debug 1.29. Steps to reproduce it:

original DEBUG
```
> debug
-h 8 FFF8
0000  0010
```
DOS-debug
```
> debug
-h 8 FFF8
0010000  0010
```

It looks to me that the operations are not done on 16 bits integers like on the original DEBUG program.

Regards, Jean

My fork lDebug has introduced an option to make the H command output compatible to MS-DOS Debug (for valid values). This must be enabled specifically however:

-r dco2 or= 1000
-h 1 2
0003  FFFF

Yes, Debug/X, as it is described in readme, has additional features, so it cannot be 100% compatible.
