The number and text of each input-output error message is given below, with the context in which it could occur and an explanation of the fault which has occurred. If the input-output statement includes an IOSTAT=STAT specifier, then an occurrence of any of the errors that follow will cause the STAT variable to become defined with the corresponding error number.

The I/O statements OPEN, CLOSE and INQUIRE are classified as Auxiliary I/O statements. The I/O statements REWIND, ENDFILE and BACKSPACE are classified as Positional I/O statements.
The IOSTAT = variable is set to -1 if an end-of-file condition occurs, to -2 if an end-of-record condition occurs (in a non-advancing READ), to the error number if one of the listed errors occurs, and to 0 if no error occurs.
Should no input/output specifier relating to the type of the occurring input/output error be given (END=, EOR=, ERR= or IOSTAT=, as appropriate), then the input/output error will terminate the user program. All units which are currently opened will be closed, and the appropriate error message will be output on Standard Error followed (if requested) by a postmortem report (see Runtime Diagnostics).
The form of an input/output error message is presented in the table below.
