Uncheck to keep F2C from inferring the types of untyped EXTERNAL procedures used only as parameters to other functions. F2C will assume such procedures are subroutines and translate them into int-valued functions.
Check to have F2C infer the types of untypes EXTERNAL procedures from from their use as parameters to previously defined or prototyped procedures. There is, unfortunately, no guarantee F2C will get it right.
Uncheck to produce the C code (and maybe a file of prototypes).
You cannot check this option unless you selected either ANSI C or C++ output in the “C Output Options” dialog.
Check to output a file of function prototypes but not produce any C code.
Uncheck to run F2C only once on a FORTRAN file, even if prototypes mightchange in a second pass.
You cannot check this option unless you selected either ANSI C or C++ output in the “C Output Options” dialog.
Check to not only output a file of function prototypes, but also perhaps re-run F2C if the prototypes might change in a second pass.
Uncheck to output only C code without a separate file of function prototypes.
You cannot uncheck this option if either of the following two options are checked. You cannot check this option unless you selected either ANSI C or C++ output in the “C Output Options” dialog.
Check to output a file of function prototypes. The file will have the same name as the FORTRAN file, but will end in “.P”.
