HP UX Fortran Software manual +moddir=directory

Table 3 Options for controlling the front end (continued)

Option	Function
+[no]implicit_none	Cause the types of identifiers to be implicitly undefined
	[defined]. The default is implicit typing
	(+noimplicit_none).
	nl
	For information about using this option, see “Disabling
	implicit typing” (page 67).
+langlvl={90default}	Issue warnings for all extensions to the Fortran standard
	(+langlvl=90). The default, +langlvl=default,
	allows extensions.
	nl
	For information about using this option, see Chapter 11,
	“Porting to HP Fortran” (page 141).
+[no]list	Write [suppress] a program listing to standard output
	during compilation. The default is +nolist.
+moddir=directory	Write .mod files to directory. The default is to write
	.mod files to the current directory.
	nl
	For information about using this option, see “The HP Fortran
	compiler environment” (page 8).
+moduleoptimize	Creates optimized module files by discarding redundant
	information. This reduces the compilation time and memory
	requirement of the compiler for nested or hierarchical
	modules.
+nls=lang	Enable 16-bit Native Language Support (NLS) in strings
	and comments in the language specified by lang.
+[no]onetrip	Execute any counter-controlled DO loop at least once
	(+onetrip). The default is +noonetrip.
	nl
	For information about using this option when porting, see
	“One-trip DO loops” (page 145).
+[no]ppu	Postpend [do not postpend] underscores at the end of
	definitions of and references to externally visible symbols.
	nl
	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.
	nl
	For information about using this option when porting, see
	“Names with appended underscores” (page 147).
+real_constant={singledouble}	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.
	nl
	For information about using this option, see “Increasing
	the precision of constants” (page 69).
+source={fixedfree 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.
	nl
	For information about using this option, see “Source
	formats” (page 147).
+[no]uppercase	Use uppercase [lowercase] for all external names. The
	default is +nouppercase.
	nl
	For information about using this option, see “Case
	sensitivity” (page 114).
