Hello, i am running a program compiled with GPC, which reads his input from a file: executable < file now, if the program tries to read more values as there are in the file, i get the following error: executable: attempt to read past end of Input (error #454 at 16ddb) My question now is: Where is this error-message created, and where can I get a list of the meanings of the error-codes? Greetings, Michael
