Hi,

How to create a folder if it doesn't exist using FORTRAN 77 language?

Regards,
Praveen

There is no standard way. Nevertheless, I often use the SYSTEM routine
which is usually provided with each FORTRAN compiler (with variants :
sometimes a subroutine, sometimes a function, sometimes a name
slightly different like FSYSTEM) :

CALL system('mkdir mydirectory')

If you want to create a directory with a path, then you must take care
about the file delimiter. I often declare an environment variable
containing the OS dependent delimiter (\ on windows and / on unix). To
get this environment variable, I use the F2003
GET_ENVIRONMENT_VARIABLE routine. With older FORTRAN compilers, the
corresponding non standard routine was often GETENV :

Very few heard of "folders" even when the '90 standard was written ;-)

Use a real programming language. Fortran is for number crunching only.

Oh! Dear me, no!
I have used C, Forth, Basic, PL/1, Pascal, Algol, Cobol, Lisp, and
other languages as well as Fortran in my 1960-to-date programming
life.

I have used Fortran F77 extensively for a variety of programming
tasks: accounting, demand reporting, games, puzzle solving,
sociological research, hotel management, process control, nuclear
physics modelling, decompiling and program charting, and many others;
actually not that much number crunching other than matrix operations
and linear programming and cost optimising.

And real programmers writing number crunching code never need to output
their data to files located in meaningful places on the disk. They just
memorise it as it flashes past on the screen. (end sarcasm mode).

Hell, very few people who use Fortran have heard of folders.
