EOF
The EOF, or End of File, error condition may be specified at the end of a program statement and in the Exit statement, but it is not accepted by the ON error statement.
Error Trap:
EOF traps three error situations: when there are no more records in the file during input (for a READ file, INPUT, or LINPUT statement), when there is not enough file space during file output (for a PRINT or WRITE statement) or when there is not enough data in DATA statements (for a READ data statement).
