XL Fortran Enterprise Edition for AIX : User's Guide - IBM

total_usertime
Returns the total user time of a process. The total user time is the sum
of the user time of a process and the total user times of its child
processes, if any.
total_systime
Returns the total system time of a process. The total system time is the
sum of the system time of the current process and the total system
times of its child processes, if any.
total_alltime
Returns the total user and system time of a process. The total user and
system time is the sum of the user and system time of the current
process and the total user and system times of their child processes, if
any.
default_recl={64 | 32}
Allows you to determine the default record size for sequential files opened
without a RECL= specifier. The suboptions are as follows:
64 Uses a 64-bit value as the default record size.
32 Uses a 32-bit value as the default record size.
The default_recl run-time option applies only in 64-bit mode. In 32-bit mode,
default_recl is ignored and the record size is 32-bit.
Use default_recl when porting 32-bit programs to 64-bit mode where a 64-bit
record length will not fit into the specified integer variable. Consider the
following:
INTEGER(4) I
OPEN (11)
INQUIRE (11, RECL=i)
A run-time error occurs in the above code sample in 64-bit mode when
default_recl=64, since the default record length of 2**63-1 does not fit into the
4-byte integer I. Specifying default_recl=32 ensures a default record size of
2**31-1, which fits into I.
For more information on the RECL= specifier, see the OPEN statement in the
XL Fortran Enterprise Edition for AIX Language Reference.
erroreof={yes | no}
Determines whether the label specified by the ERR= specifier is to be branched
to if no END= specifier is present when an end-of-file condition is
encountered.
err_recovery={yes | no}
If you set this run-time option to no, the program stops if there is a
recoverable error while executing an I/O statement with no IOSTAT= or ERR=
specifiers. By default, the program takes some recovery action and continues
when one of these statements encounters a recoverable error. Setting cnverr to
yes and err_recovery to no can cause conversion errors to halt the program.
iostat_end={extended | 2003std}
Sets the IOSTAT values based on the XL Fortran definition or the Fortran 2003
Draft Standard when end-of-file and end-of-record conditions occur. The
suboptions are as follows:

extended
Sets the IOSTAT variables based on XL Fortran’s definition of values
and conditions.
