33 ; This is the error code mapping table for INT 21 errors. This table defines
34 ; those error codes which are "allowed" for each system call. If the error
35 ; code ABOUT to be returned is not "allowed" for the call, the correct action
36 ; is to return the "real" error via Extended error, and one of the allowed
37 ; errors on the actual call.
38 ;
39 ; The table is organized as follows:
40 ;
41 ; Each entry in the table is of variable size, but the first
42 ; two bytes are always:
43 ;
44 ; Call#,Cnt of bytes following this byte
45 ;
46 ; EXAMPLE:
47 ; Call 61 (OPEN)
48 ;
49 ; DB 61,5,12,3,2,4,5
50 ;
51 ; 61 is the AH INT 21 call value for OPEN.
52 ; 5 indicates that there are 5 bytes after this byte (12,3,2,4,5).
53 ; Next five bytes are those error codes which are "allowed" on OPEN.
54 ; The order of these values is not important EXCEPT FOR THE LAST ONE (in
55 ; this case 5). The last value will be the one returned on the call if
56 ; the "real" error is not one of the allowed ones.
57 ;
58 ; There are a number of calls (for instance all of the FCB calls) for which
59 ; there is NO entry. This means that NO error codes are returned on this
60 ; call, so set up an Extended error and leave the current error code alone.
61 ;
62 ; The table is terminated by a call value of 0FFh
