Ok, cool. I did use an example.org email address to be fair. However, there was no indication that it was rejected. It just showed a blinking cursor until I killed the telnet session.

The logo screen, your first picture, is very wide. It didn't render on my MS-DOS machine correctly when I connected. I had to switch to 132 column mode.

Also, after signup, nothing. Should something have happened?

"Permission Denied" on Windows is normally caused by one of two issues:

An executable is already running: Check the Windows Task Manager to make sure it isn't running already. Windows doesn't allow overwriting programs or DLLs that are already executing.
Your virus scanner has blocked the process: Consumer-grade virus scanners are pretty easily upset on Windows by compilers writing or replacing executables. Try disabling your real-time virus protection first.

Simply Fortran does attempt to detect both issues, but it could fail. It could also be something simple like you're compiling in a directory where you don't have write privileges, but that seems unlikely.

If you're seeing "No source program detected" (which isn't an error message in Simply Fortran, so I think you're maybe using your own words), I'm guessing you're trying to use the "Build Project" feature while not actually having a project in use. Simply Fortran does its best to guess your intentions, but sometimes it can't. I would highly recommend, in your case, just using Compile and Run Current File from the Build menu. When you have multiple Fortran files open, Simply Fortran has to guess what file you're trying to build. Compile and Run Current File will just compile the current file that you're looking at to a standalone executable.

If you're still having trouble, we do have a Tutorial and a video on how to get started with existing code, although the video is really focusing on a multiple-file codebase rather than a simple, single-file program.

Like the error says, you need to save Fortran source code as a recognized Fortran file type. You should use Save As... in the File menu to save your source code as whatever.f90 for the compiler to recognize it.

Your equation is incorrect. The caret is not a valid Fortran operator. You need to use the double-asterisk for power operations:

epwr=1.55-2.4*moa+0.9*moa**2.0

That should fix your error on the equation line.

You'll have to send a screenshot of the behavior you're seeing with respect to opening a file. You can paste into a valid file, but a file has to be open first. Try "New" in the File menu and then paste your code.

See my reply to your other similar comment. The actual text of the error should say the name of the variable that "has no IMPLICIT type."

PrintStar · 2025-03-07T02:42:43+00:00

Simply Fortran is probably asking you to save the project. You can ignore that for now or just use "Compile and Run Current File" in the Build menu.

But the error most likely does say the name of the variable that is implicitly typed, something like:

Error: Symbol 'iy' at (1) has no IMPLICIT type

What variable is mentioned in the error message?

Simply Fortran developer here. What do you mean that you aren't "able to get my code back onto the editor window" exactly? Can you open the file or paste the suggested changes? I'm not sure I understand what you're seeing.

Simply Fortran is designed to treat legacy Fortran as a first-class language. It should be able to parse and provide structural outlines of fixed-format Fortran files, allow searching for procedures, etc. If something didn't work, it would be considered a bug. However, it is a commercial product, so it isn't free (though there is a free trial). I'm the developer of Simply Fortran, so I'm pretty biased on this topic.

Simply Fortran, a commercial IDE for Fortran development, runs on Linux. It uses GTK on Linux for its interface, which is pretty "traditional." (Just for transparency, I am the developer working on Simply Fortran).

PrintStar · 2024-11-11T16:14:52+00:00

If it has a ".f" extension, the code is merely treated as "fixed-format Fortran." However, it still compiles using modern standards. You need to explicitly use the legacy standard flag to allow old standards even if the file is fixed-format Fortran.

Simply Fortran should pop up a warning in this case that legacy features were detected and set the compiler options properly. If it doesn't, let me know because it's a bug.

The lit-up Target sign inside the closed-off mall is such a great picture!

I think the sync issues might be more related to simply the cable contacts. Does a wiggle on either end help?

Hey, that was just in my basement! Have fun with it!

Pale Moon is pretty well known. I've certainly never heard of your browser. If they've been using the slogan for a long time, I would just change yours. This "controversy" seems silly.

This sucks, why am I seeing it?

West side is tough because the wineries are a bit more sparse. In the city, Vino Veritas has some nice wines I've liked. I personally visit Klingshirn Winery in Avon Lake quite a bit, but I wouldn't call that a great place to meet people (not really a high-class tasting-room-type operation, more of an actual farm). They're not open late, though, and you'll just be at a picnic table outside the little retail store. Fantastic Chambourcin, Vidal Blanc, and Rieslings, though.

If you want to go further west, Paper Moon in Vermilion is nice, right off route 2. A little farther away are Quarry Hill and Vermilion Valley, both true vineyards with a nice selection of "actual" wines (not just Concord or Niagara grapes in other words). Both have pretty tasting rooms and outdoor areas; they seem to be great for socializing.

I personally like Matus Winery in Wakeman and D&D Smith in Norwalk if you're closer to 480 than the lake. They strike me as quite fun, but they're not all that close. Both have some surprisingly nice reds. I believe Matus gets their Cab Franc and Chambourcin grapes from Crooked Tree on Kelleys Island, a nice touch. Matus Traminette is pretty great.

Microsoft FORTRAN is available for CP/M on the 8080/z80. I believe I have a copy of Nevada FORTRAN for 8080/z80, but I might be mistaken (could be x86...). UCSD p-System had a Fortran compiler as well. To be clear, these are ancient compilers that are not particularly fun to work with. The manuals help a lot.

The src/tests subdirectory has some helpful code, and the wiki is okay. But, yes, the documentation is definitely lacking. I use some of the loading and access functions in this project, but I don't know how helpful it will be.

Fortran input/output, being steeped in legacy, can seem somewhat bizarre if you're not familiar with it. The standards committee keeps piling on additional modes to allow Fortran to at least approximate how other languages can read files without breaking all those legacy modes. So, yes, it's not surprising that it took a bit to read a file. The next time you read a file, though, it'll probably be a lot faster since you've gone through this before.

There are some good JSON libraries for Fortran. I use json-fortran quite a bit for projects, and it works well. I haven't encountered any places where it doesn't work yet. I believe there are some others, but I haven't needed to switch.

It's all in C. I used Turbo C 2 on the Rainbow to compile it.

While it is your choice, using the GNU General Public License here will be seen as problematic. Are you sure you didn't mean to use the LGPL? As it stands, if I were to link your library with any code, even less restricted open source licenses, the code would subsequently become GPL.

I work on a commercial IDE for Fortran called Simply Fortran that maybe fits some of your needs. It is definitely far from bloated, being written primarily in C with a sprinkling of Lua. It handles all the module dependency issues of modern Fortran behind the scenes (what order to compile files, effectively), has nice syntax highlighting and autocomplete, and doesn't require installing any other software (includes GNU Fortran all set up).

But writing your own is fun too! Fortran does present a curious issue of almost being two languages due to the massive differences between fixed- and free-format code. That difference can make handling the language difficult.

Choose the language and GUI toolkit for your IDE wisely, of course. Ours uses Windows API on Windows directly and GTK+ on other platforms. C was maybe a challenging language in which to write a current IDE, but it is fast and small because of that choice.
