For Itanium architecture, the default is +ppu. For
PA-RISC 64-bit architecture, the default is +ppu. For
PA-RISC 32-bit architecture, the default is +noppu.
For information about using this option when porting, see
“Names with appended underscores” on page 242.
+real_constant={single|d
ouble}
Treat all single-precision real and complex constants as
either single-precision (+real_constant=single) or
double-precision (+real_constant=double). The default is
+real_constant=single. This option has no effect on
constants that are explicitly sized or when the +autodbl or
+autodbl4 option is specified.
For information about using this option, see “Increasing the
precision of constants” on page 103.
+source={fixed|free|
default}
Accept source files in fixed format (+source=fixed) or free
format (+source=free). The default, +source=default, is
free for .f90 files and fixed for .f and .F source files.
For information about using this option, see “Source
formats” on page 242.
+[no]uppercase Use uppercase [lowercase] for all external names. The
default is +nouppercase.
For information about using this option, see “Case
