Assume the default \fIlibF77\fR -and \fIlibI77\fR: allow only INTEGER\(**4 (and no LOGICAL) -variables in INQUIREs. Option -.L -I4 -confirms the default rendering of INTEGER as long int. -.TP -.B -onetrip -Compile DO loops that are performed at least once if reached. -(Fortran 77 DO loops are not performed at all if the upper limit is smaller than the lower limit.) -.TP -.B -U -Honor the case of variable and external names.

Option -.B -Ps -implies -.B -P -and gives exit status 4 if rerunning -.I f\^2c -may change prototypes or declarations. -.TP -.B -p -Supply preprocessor definitions to make common-block members -look like local variables. -.TP -.B -R -Do not promote -.SM REAL -functions and operations to -.SM DOUBLE PRECISION. -Option -.L -!R -confirms the default, which imitates -.IR f\^77 . -.TP -.B -r -Cast values of REAL functions (including intrinsics) to REAL. -.TP -.B -r8 -Promote -.SM REAL -to -.SM DOUBLE PRECISION, COMPLEX -to -.SM DOUBLE COMPLEX. -.TP -.B -s -Preserve multidimensional subscripts. -.TP -.BI -T dir -Put temporary files in directory -.I dir. -.TP -.B -w8 -Suppress warnings when -.SM COMMON -or -.SM EQUIVALENCE -forces odd-word alignment of doubles. -.TP -.BI -W n -Assume -.I n -characters/word (default 4) -when initializing numeric variables with character data. -.TP -.B -z -Do not implicitly recognize -.SM DOUBLE COMPLEX. -.TP -.B -!bs -Do not recognize \fIb\fRack\fIs\fRlash escapes -(\e", \e', \e0, \e\e, \eb, \ef, \en, \er, \et, \ev) in character strings. -.TP -.B -!c -Inhibit C output, but produce -.B -P -output. -.TP -.B -!I -Reject -.B include -statements. -.TP -.B -!i8 -Disallow -.SM INTEGER*8. -.TP -.B -!it -Don't infer types of untyped -.SM EXTERNAL -procedures from use as parameters to previously defined or prototyped -procedures. -.TP -.B -!P -Do not attempt to infer -.SM ANSI -or C++ -prototypes from usage. -.PP -The resulting C invokes the support routines of -.IR f\^77 ; -object code should be loaded by -.I f\^77 -or with -.IR ld (1) -or -.IR cc (1) -options -.BR "-lF77 -lI77 -lm" . -Calling conventions -are those of -.IR f\&77 : -see the reference below. -.br -.SH FILES -.TP -.IB file .[fF] -input file -.TP -.B *.c -output file -.TP -.F /usr/include/f2c.h -header file -.TP -.F /usr/lib/libF77.a -intrinsic function library -.TP -.F /usr/lib/libI77.a -Fortran I/O library -.TP -.F /lib/libc.a -C library, see section 3 -.SH "SEE ALSO" -S.
