vb调用fortran

（1）在Fortran PowerStation 4.0下，编制可供VB调用的.dll文件，示例代码： subroutine forcx(a,b,c) !ms$if .not. defined(linkdirect) !ms$attributes dllexport :: HWJSVB !ms$endif integer a,b,c a=b+c end （2） 在VB下编写如下代码： Private Declare Sub forcx B Lib "dll.dll" Alias "_ FORCX @12" (ByRef a As integer, ByRef b As integer, ByRef c As integer) Sub callfor() Dim a as integer, b as integer ,c as integer B=1 : c=2 Call forcx(a,b,c) End
