How to create a new directory from Force Fortran 2.0 -


i need create new directory code able write data file it.

i using force fortran 2.0 windows 8 , wondering if syntax going vary 1 operating system other due front/backslash issue.

force fortran uses older compilers (g77, g95, gfortran [unknown version]), i'll present solution system. compilers support it, it's better use standard-conforming execute_command_line.

you can use mkdir, present on both windows , unix machines. default, mkdir creates folder , (non-existing) parent folders on windows. has explicitly given on unix (-p). using system can execute fortran: 

program test   implicit none #ifdef _win32   character(len=*),parameter :: mkdir = 'mkdir '   !                                           ^   !                    blank intentional!  #else   character(len=*),parameter :: mkdir = 'mkdir -p '   !                                              ^   !                       blank intentional!  #endif   integer :: stat    stat = system( mkdir // 'testfolder' )   if ( stat /= 0 )     print *, 'mkdir: failed create folder! '   endif end program

you still need create routine takes care of correct folder delimiter, here quick&dirty example:

module conv_mod contains   function conv2win(str) result(res)     implicit none     character(len=*),intent(in) :: str     character(len=len(str))     :: res     integer                     ::      res = str     i=1,len(res)       if ( res(i:i) == '/' ) res(i:i) = '\'     enddo !   end function    function conv2unix(str) result(res)     implicit none     character(len=*),intent(in) :: str     character(len=len(str))     :: res     integer                     ::      res = str     i=1,len(res)       if ( res(i:i) == '\' ) res(i:i) = '/'     enddo !   end function end module  program conv   use conv_mod   print *,conv2win('some/path')   print *,conv2win('some\path')   print *,conv2unix('some\path') end program

this doesn't take care of things c:\, though... @vladimirf noted, can use / in windows, too. still need convert backslash / in unix.

i have created angular spa webapi backend using adal js authentication.as there no roles in ad, need manually add role claims in order give users access different api controllers. the roles stored in database. expecting inject claim through call webapi after authentication ad. webapi code might this. identity.addclaim(new claim("role", "user")); var ticket = new authenticationticket(identity, props); var accesstoken = startup.oauthbeareroptions.accesstokenformat.protect(ticket); is possible replace adal idtoken new token? is viable solution or there other better way handle this? as initial token generated azuread, possible edit token add new claim? appreciated. graph api supporting group claims. see here: http://justazure.com/azure-active-directory-part-4-group-claims/ if @ examples on page, users assigned groups , app can check group in claims. in current version of portal, need app manifest , modify it.
