IOMSG = variable
The IOMSG= specifier is permitted in all input/output statements.
The variable must be a scalar character with default kind;
its length should be sufficient to hold any message of interest.

The IOMSG= specifier causes the
specified variable to be defined with an explanatory message if an
error, end-of-file or end-of-record condition occurs during
execution of the input/output statement (if the variable is too
short, the message will be truncated). If no such condition
occurs, the variable is unchanged.
Note that if no IOSTAT= and no appropriate END=, EOR= or ERR=
specifier appears, the program will be terminated on that
condition; therefore it is necessary to use one of these together
with the IOMSG= specifier if it is to be useful.
