1988 Fortran code

Hi, everybody!

Learned Fortran language a long time ago, back in 1992, or so.

Now, back in the business, i got an 1988 fortran code that i need to put to work.

Manage to change some lines and put it to work under Visual Studio Code debug application.

Strangly, i can't compile to an executable, using any of the compilers i tried till now, resulting in some really strange errors (at least for me).

What can be the problem, and how can i sort it out?

Really desperate with this...

Without the code or at the very least the error messages it will be impossible for us to help you. Can you show the code? There may be any number of things causing such messages and such a failure to build the program.

Hi, Arjen!


I can send you the code, no problem with that, but it have 1135 lines... please check if it was properly attach to this message.
The error codes were different from compiler to compiler and all very strange, like the one regarding the start sentence "program", which was expected to have a digit on it!
 
Thank you in advance for your kind attention.

We I renamed your file console3.f90 and compiled it. There are some errors with FORMAT statements with lower case "L" where "1" seems to be the intention and a couple of spurious spaces e.g. "F6 . 1" rather than "F6.1" having corrected those it compiles and runs  up to the point it asks me for some input.... The Modified version below. It does have a number of warnings and I had to turn standards checking off also.

Thank you so much Andrew!

Had some issues with those before, too, but thought they were solved when i first saw the programm asking for the first imputs.

Thank you so much!

I'll work from here! Let's see what i'll get with the compiler.

Do you advise some compiler in particular?

These extra spaces in formats might be due to the conversion from fixed form to free form. In fixed form spaces are only significant inside string literals.

I just used the latest OneApi compiler, it is free to download and use.
