In my mind, the "convert" aspect will be mainly to "clean up" FORTRAN code to make use of standard C interoperability facilities. Here's a simple example, here the Fortran code is in modern free-form style, but the same would work with fixed-form too: module m use, intrinsic :: ...

方法1:使用内置函数CONVERT和CHAR 使用内置函数CONVERT和CHAR可以有效地将浮点数转换为字符串。以下是使用这种方法的示例代码: fortran program float_to_string implicit none real :: number = 3.14159 character(len=20) :: str_number str_number = char(convert(number), len=str_number) write(*,*) str_...
It converts all uppercase letters to lowercase letters, except within character-string constants. There are two usual solutions to the uppercase/lowercase problem:In the C subprogram, make the name of the C function all lowercase. Compile the f77 program with the -U option, which tells f77 ...
此子程序是一 .f 文件，可以将一个字符串中的小写字母转换为大写字母。FORTRAN中并没有直接转换字母大小写的内部函数，必须使用内码转换，即先把字母的ACSII码读出，然后减去32，再转换为字母，就达到目的了 c c c c c ## subroutine upcase -- convert string to all upper case c c c...

The next revision of the standard will (probably) have a F_C_STRING function that returns a NUL-terminated copy of its argument, making this a bit cleaner. (It also will probably have a C_F_STRPOINTER subroutine to convert a NUL-terminated string to a CHARACTER, POINTER of ...
