Ü  %EOF(filename)

·    This built-in function is used to detect end-of file, beginning of file, or subfile full conditions while performing a file operation similar to resulting indicator.

·    So, instead of checking any resulting indicator we simply use %EOF to check if the end of file is reached.

·    %EOF returns '1' if end-of file, beginning of file, or subfile full condition is found ; otherwise, it returns '0'.

·    READ, READC and READE return %EOF=*ON if the end of file is reached.

·    READP and READPE return %EOF=*ON if the beginning of file is reached.

·    WRITE operation returns %EOF=*ON if the WRITE operation to a subfile detail record returned a subfile-full condition.

·    If %EOF=*ON and we perform CHAIN operation, then CHAIN operation on successful search sets %EOF=*OFF.

·    OPEN, SETGT, SETLL on successful operations, sets %EOF=*OFF.
