FOR$IOS_F6304. An illegal value was used with the STATUS option.

STATUS accepts the following values:

• 'KEEP' or 'DELETE' when used with CLOSE statements
• 'OLD', 'NEW', 'SCRATCH', or 'UNKNOWN' when used with OPEN statements

FOR$IOS_F6305. An illegal value was used with the MODE option.

MODE accepts the values 'READ', 'WRITE', or 'READWRITE'.

FOR$IOS_F6306. An illegal value was used with the ACCESS option.

ACCESS accepts the values 'SEQUENTIAL' and 'DIRECT'.

FOR$IOS_F6307. An illegal value was used with the BLANK option.

BLANK accepts the values 'NULL' and 'ZERO'.

FOR$IOS_F6308. An illegal value was used with the FORM option.

FORM accepts the following values: 'FORMATTED', 'UNFORMATTED', and 'BINARY'.

FOR$IOS_F6309. An illegal value was used with the SHARE option.

SHARE accepts the values 'COMPAT', 'DENYRW', 'DENYWR', 'DENYRD', and 'DENYNONE'.

FOR$IOS_F6311. An invalid number was specified as the record number for a direct-access file.

The first valid record number for direct-access files is 1.

FOR$IOS_F6312. In an INQUIRE statement, the NUMBER option was specified for the file associated with * (console).

FOR$IOS_F6314. An illegal unit number was specified.

Legal unit numbers can range from 0 through 2**31-1, inclusive.

FOR$IOS_F6315. A negative or zero record length was specified for a direct file.

The smallest valid record length for direct files is 1.

FOR$IOS_F6316. The program attempted to ALLOCATE an already allocated array.

FOR$IOS_F6317. The size specified for an array in an ALLOCATE statement must be greater than zero.

FOR$IOS_F6318.

FOR$IOS_F6319. The program attempted to DEALLOCATE an array that was never allocated.

FOR$IOS_F6400. A BACKSPACE statement specified a unit connected to a terminal device such as a terminal or printer.

FOR$IOS_F6401. An EOF intrinsic function specified a unit connected to a terminal device such as a terminal or printer.

FOR$IOS_F6402. An ENDFILE statement specified a unit connected to a terminal device such as a terminal or printer.

FOR$IOS_F6403. A REWIND statement specified a unit connected to a terminal device such as a terminal or printer.

FOR$IOS_F6404. A CLOSE statement specified STATUS='DELETE' for a read-only file.

FOR$IOS_F6405. The program tried to access a file after executing an ENDFILE statement or after it encountered the end-of-file record during a read operation.

A BACKSPACE, REWIND, or OPEN statement must be used to reposition the file before execution of any I/O statement that transfers data.

FOR$IOS_F6406.

FOR$IOS_F6407. More than 131 characters were input to a record of a unit connected to the terminal (keyboard). Note that the operating system may impose additional limits on the number of characters that can be input to the terminal in a single record.

FOR$IOS_F6408. If you have record lengths that exceed the buffer size associated with the record, (for instance, the record is a file with the buffer set by BLOCKSIZE in the OPEN statement), either you should not do left tabbing within the record, or you should not use commas as field delimiters. This is because commas are disabled as input field delimiters if left tabbing leaves the record positioned in a previous buffer.

For example, consider you have a file LONG.DAT that is one continuous record with data fields separated by commas. You then set the buffer associated with the file to 512 bytes, read more than one buffer size of data, tab left to data in the previous buffer, and attempt to read further data, as follows:

    INTEGER value(300)
    OPEN (1, FILE = 'LONG.DAT', BLOCKSIZE = 512)
    READ (1, 100) (value(i), i = 1, 300)
100 FORMAT (290I2,TL50,10I2)
 

FOR$IOS_F6413. The program tried to connect an already connected file to a new unit.

A file can be connected to only one unit at a time.

FOR$IOS_F6414.

This error can be caused by one of the following:

• The filename specified in an OPEN statement was a directory.
• An OPEN statement tried to open a read-only file for writing.
• The file was opened with SHARE='DENYRW' by another process.

FOR$IOS_F6415. An OPEN statement specified STATUS='NEW' for a file that already exists.

FOR$IOS_F6416. An OPEN statement specified STATUS='OLD' for a specified file or a directory path that does not exist.

FOR$IOS_F6417. The program exceeded the number of open files the operating system allows.

FOR$IOS_F6418. The program exceeded the number of units that can be connected at one time. Units are connected with the OPEN statement.

FOR$IOS_F6419. The file was opened with FORM='UNFORMATTED' and ACCESS='SEQUENTIAL', but its internal physical structure was incorrect or inconsistent. Possible causes: the file was created in another mode or by a non-Fortran program.

FOR$IOS_F6420. A statement such as BACKSPACE or ENDFILE specified a file that had not yet been opened. (The READ and WRITE statements do not cause this problem because they prompt you for a file if the file has not been opened yet.)

FOR$IOS_F6421. The program tried to transfer data to a file that was opened in read-only mode or locked against writing.

The error message may indicate a CLOSE error when the fault is actually coming from WRITE. This is because the error is not discovered until the program tries to write buffered data when it closes the file.

FOR$IOS_F6422. The program tried to transfer data to a file residing on a device (such as a hard disk) that was out of storage space.

FOR$IOS_F6423. Too many threads were active simultaneously. At most, 32 threads can be active at one time. Close any unnecessary processes or child windows within your application.

FOR$IOS_F6424.

FOR$IOS_F6425. The BACKSPACE statement is not allowed in files opened with MODE='WRITE' (write-only status) because BACKSPACE requires reading the previous record in the file to provide positioning.

Resolve the problem by giving the file read access or by avoiding the BACKSPACE statement. Note that the REWIND statement is valid for files opened as write-only.

FOR$IOS_F6500. The program tried to read from a file that was not opened for reading or was locked.

FOR$IOS_F6501. The program tried to read more data than the file contains.

FOR$IOS_F6502. When the i*c form is used in list-directed input, the i must be a positive integer. For example, consider the following statement:

  READ(*,*) a, b
