Compare up to 64k bytes of memory at two locations in storage.

Syntax:

ÄÄÄÄ C  ÄÄÄ  addr1  ÄÄÄÄÄ n ÄÄÄÄ  addr2  ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ

Parameters:

addr1

The address of the beginning of the first location to compare with the second. This address is assumed to be in #selector:offset format. If the selector is omitted then the current DS selector is assumed.
n
The offset from addr1 of the last byte to compare (that is, the length of the range less 1).
addr2
The address of the beginning of the second location to compare with the first. An address expression may be specified. This address is assumed to be in #selector:offset format. If the selector is omitted then the current DS selector is assumed.

Results & Notes:

Storage is compared, if no differences are found then the command prompt is displayed. If either of the addresses is invalid then an error message is displayed.

Where differences are found in the address range then they are displayed in the following way:

001f:00000000 57 4f 001f:00000003001f:00000001 50 32 001f:00000004
001f:00000003 57 4f 001f:00000006

The addresses of the two differing locations are displayed outermost and the bytes at those locations are displayed in columns 2 and 3.
