ERROR CODES

GEMDOS/BIOS Errors

Upon return from most GEMDOS and BIOS functions, register D0 contains a longword error code describing the failure or success of an operation. The BIOS uses error codes -1 to -31 while GEMDOS uses error codes -32 and lower. A return value of 0 always indicates success. The error codes and their meanings are as follows:
