other operations on the logical unit may be performed between the READ and
REWRITE statements.
55
severe (55): DELETE error
FOR$IOS_DELERR. An error condition was detected by the DIGITAL Fortran RTL
I/O system during execution of a DELETE statement.
57
severe (57): FIND error
FOR$IOS_FINERR. The DIGITAL Fortran RTL I/O system detected an error
condition during execution of a FIND statement.
58¹
info (58): Format syntax error at or near xx
FOR$IOS_FMTSYN. Check the statement containing xx, a character substring from the
format string, for a format syntax error. For more information, see the FORMAT
statement.
59
severe (59): List-directed I/O syntax error
FOR$IOS_LISIO_SYN². The data in a list-directed input record had an invalid format,
or the type of the constant was incompatible with the corresponding variable. The value
of the variable was unchanged.
60
severe (60): Infinite format loop
FOR$IOS_INFFORLOO. The format associated with an I/O statement that included an
I/O list had no field descriptors to use in transferring those values.
¹Identifies errors not returned by IOSTAT.
²The ERR transfer is taken after completion of the I/O statement for error number 59. The resulting
file status and record position are the same as if no error had occurred. However, other I/O errors take
the ERR transfer as soon as the error is detected, so file status and record position are undefined.
Run-Time Errors 61 Through 108
This section describes in detail Visual Fortran run-time errors 61 through 108.
In the following table, the first column lists error numbers returned to IOSTAT variables when an I/O
error is detected.
The first line of the second column provides the message as it is displayed (following forrtl:),
including the severity level, message number, and the message text. The following lines of the second
column contain the status condition symbol (such as FOR$IOS_INCRECTYP) and an explanation of
the message.
For information about the severity levels, see the Introduction.
