The compiler will use more accurate cosd,sind , andtand
intrinsics, than the standard ones. While the standard ones
+trigdacc
have some accuracy problems with the boundary cases
(i.e., cosd(90)needs to be 0.0), these new intrinsics get
these cases right.
NOTE: +trigdaccoption is not valid on HP
Itanium®-based systems.
+ttybufcontrols tty buffering, using buffered output.
+nottybufuses unbuffered output. The default is buffered
+[no]ttybuf
output (+ttybuf).The +ttybufoption forces buffered
output even on systems whose default is unbuffered output.
The +[no]ttybufoption is recognized only when the
main program is a Fortran program. If the main program
is written in another language, use
theTTYUNBUFenvironment variable (see f90(1).
-Uundefines or removes any initial definition of namein
the C preprocessor (cpp). See thecpp (1) in the HP-UX
Referencefor details.
-Uname
+U77option invokes support for the BSD 3F library,
libU77, which provides an HP Fortran interface to some
+[no]U77
of the libc system routines. To call routines in this library,
you must compile and link with +U77. For information
about these routines, see the HP Fortran Programmer’s
Reference.of an unsatisfied symbol. If the libU77 name
is the same as a libcname, the name might resolve to a
libcname. This situation does not cause an error at
compile time, but can produce unpredictable results.
+uppercaseuses uppercase for external names. The
default, +nouppercase, is to convert external names to
lowercase.
If you need to control the case of specific names, use
the$HP$ ALIAS directive, as described in “$HP$ ALIAS”
on page 208.
+[no]uppercase
+usage lists and briefly describes all of the command-line
options currently supported by the HP Fortran compiler.
No compile occurs.
+usage
-venables the verbose mode, producing a step-by-step
description of the compilation process on the standard
error output.
-v
+versiondisplays compiler version information only; no
compilation occurs.
+version
-wsuppresses warning messages. If this option is omitted,
warnings are sent to standard error.
