A valid format specification is required on all READ and WRITE
statements.
The format specification is specified by:
.millust begin
[FMT=] <format identifier>
.millust end
.pc
.sy <format identifier>
is one of the following: statement label, integer variable-name,
character array-name, character expression, or *.
.errnote IL-02 the UNIT may not be an internal file for this statement

4 but another size was specified.
These include the EXIST, OPENED, RECL, IOSTAT, NEXTREC, and NUMBER.
The name used in the ASSIGN statement must also be of size 4 but a
different size was specified.
.errnote IL-05 missing or unrecognizable control list item %s1

An optional asterisk for list-directed formatting is an extension to
the FORTRAN 77 language.
The standard FORTRAN 77 language specifies that an asterisk is required.
.errnote IL-10 missing or improper unit identification
.pc
The control specifier, UNIT, in the I/O statement is either missing
or identifies an improper unit.
The unit specifier specifies an external unit or internal file.
The external unit identifier is a non-negative integer expression or
an asterisk.
The internal file identifier is character variable, character array,
character array element, or character substring.
.errnote IL-11 missing unit identification or file specification
.pc
An identifier to specifically identify the required file is missing.
The UNIT specifier is used to identify the external unit or internal
file.
The FILE specifier in the INQUIRE and OPEN statements is used to
identify the file name.
.errnote IL-12 asterisk unit identifier not allowed in %s1 statement
.pc
The BACKSPACE, CLOSE, ENDFILE, INQUIRE, OPEN, and REWIND statements
require the external unit identifier be an unsigned positive integer
from 0 to 999.
.errnote IL-13 cannot have both UNIT and FILE specifier

There are two valid forms of the INQUIRE statement; INQUIRE by FILE
and INQUIRE by UNIT.
Both of these specifiers cannot be specified in the same statement.
.errnote IL-14 internal files require sequential access
.pc
An attempt has been made to randomly access an internal file.
Internal files may only be accessed sequentially.
.errnote IL-15 END specifier with REC specifier is not FORTRAN 77 standard
.pc
The FORTRAN 77 standard specifies that an end-of-file condition can only
occur with a file connected for sequential access or an internal file.
The REC specifier indicates that the file is connected for direct access.
This extension allows the programmer to detect an end-of-file condition when
reading the records sequentially from a file connected for direct access.

The type declared in the IMPLICIT statement is not one of INTEGER,
REAL, DOUBLE PRECISION, COMPLEX, LOGICAL or CHARACTER.
.errnote IM-04 (*) length specifier in an IMPLICIT statement is not FORTRAN 77 standard
.pc
A character length specified of (*) in an IMPLICIT statement is an
extension to the FORTRAN 77 language.
.errnote IM-05 IMPLICIT NONE allowed once or not allowed with other IMPLICIT statements
.pc
The IMPLICIT NONE statement must be the only IMPLICIT statement in
the program unit in which it appears.
Only one IMPLICIT NONE statement is allowed in a program unit.
.errtail
.errhead Input/Output
.errnote IO-01 BACKSPACE statement requires sequential access mode
.pc
The file connected to the unit specified in the BACKSPACE statement
has not been opened for sequential access.
.errnote IO-02 input/output is already active
.pc
An attempt has been made to read or write a record when there is an
already active read or write in progress.
The execution of a READ or WRITE statement has caused transfer to a
function that contains a READ or WRITE statement.
.errnote IO-03 ENDFILE statement requires sequential access mode
.pc
The specified external unit identifier must be connected for
sequential access but was connected for direct access.
.errnote IO-04 formatted connection requires formatted input/output statements
.pc
The FORM specifier in the OPEN statement specifies FORMATTED and the
subsequent READ and/or WRITE statement does not use formatted I/O.
If the FORM specifier has been omitted and access is SEQUENTIAL then
FORMATTED is assumed.
If the access is DIRECT then UNFORMATTED is assumed.
.errnote IO-05 unformatted connection requires unformatted input/output statements
.pc
The FORM specifier in the OPEN statement specifies UNFORMATTED and
the subsequent READ and/or WRITE statement uses formatted I/O.

FORMATTED is assumed.
If the access is DIRECT then UNFORMATTED is assumed.
.errnote IO-06 REWIND statement requires sequential access
.pc
The external unit identifier is not connected to a sequential file.
The REWIND statement positions to the first record in the file.
.errnote IO-07 bad character in input field
.pc
The data received from the record in a file does not match the type
of the input list item.
.errnote IO-08 BLANK specifier requires FORM specifier to be 'FORMATTED'
.pc
In the OPEN statement, the BLANK specifier may only be used when the
FORM specifier has the value of FORMATTED.
The BLANK specifier indicates whether blanks are treated as zeroes or
ignored.
.errnote IO-09 system file error - %s1
.pc
A system error has occurred while attempting to access a file.
The I/O system error message is displayed.
.errnote IO-10 format specification does not match data type
.pc
A format specification in the FMT specifier or FORMAT statement
specifies data of one type and the variable list specifies data of a
different type.
.errnote IO-11 input item does not match the data type of list variable
.pc
In the READ statement, the data type of a variable listed is not of
the same data type in the data file.
For example, non-digit character data being read into an integer
item.
.errnote IO-12 internal file is full
.pc
The internal file is full of data.
If a file is a variable then the file may only contain one record.
If the file is a character array then there can be one record for
each array element.
.errnote IO-13 RECL specifier is invalid
.pc
In the OPEN statement, the record length specifier must be a positive
integer expression.
.errnote IO-14 invalid STATUS specifier in CLOSE statement

RECL specifier must be given.
.errnote IO-18 REC specifier required in direct access input/output statements
.pc
In the OPEN statement, the ACCESS  specified was DIRECT.
All subsequent input/output statements for that file must use the REC
specifier to indicate which record to access.
.errnote IO-19 REC specifier not allowed in sequential access input/output statements
.pc
In the OPEN statement, the ACCESS specified was SEQUENTIAL.
The REC specifier may not be used in subsequent I/O statements for
that file.
The REC specifier is used to indicate which record to access when
access is DIRECT.
.errnote IO-20 %s1 specifier may not change in a subsequent OPEN statement
.pc
The %s1 specifier may not be changed on a subsequent OPEN statement
for the same file, in the same program.
Only the BLANK specifier may be changed.
.errnote IO-21 invalid STATUS specifier for given file
.pc
In the OPEN statement, the STATUS specifier does not match with the
actual file status: OLD means the file must exist, NEW means the file
must not exist.
If the STATUS specifier is omitted, UNKNOWN is assumed.
.errnote IO-22 invalid STATUS specifier/FILE specifier combination
.pc
In the OPEN statement, if the STATUS is SCRATCH, the FILE specifier
cannot be used.
If the STATUS is NEW or OLD, the FILE specifier must be given.
.errnote IO-23 record size exceeded during unformatted input/output
.pc
This error is issued when the size of an i/o list item exceeds the
maximum record size of the file.
The record size can be specified using the RECL= specified in the OPEN
