    Fortran Input
AI Thread Summary
To input a word in Fortran instead of a number, users can utilize the `read` statement to capture string input. For example, declaring a character variable and using `read` allows for string comparison. The provided code snippet demonstrates how to prompt for a name and respond based on the input. In Fortran 95, the equality operator can be `==`, while earlier versions may require `.EQ.` for comparisons. This approach effectively enables the use of words as input in Fortran programs.

I would like to input a word in the fortran command line rather than a number. For example, if I wanted to exit a program with the word 'exit' how would that be done?

Thanks for the help :D

in the fortran command line
Do you really mean "command line" here, as in "command line parameter". Or are you actually inquiring about reading (and comparing) strings.

I don't think there is a way to access command line parameters in standard fortran (at least up to F95) so I assume you mean the latter.

Code:
character(20) name

print "(a$)", 'Enter your name> '
read *, name
if (name == 'uart') print *,'Cool name dude.'

The above works for me in Fortran 95 (the gnu g95 compiler). In earlier Fortran versions you might have to use .EQ. instead of ==
 
That is exactly what I was looking for. I didn't know how to use words as input for Fortran until now :DDDDDDDDDDDDDD Thank you so much.

Dear Peeps I have posted a few questions about programing on this sectio of the PF forum. I want to ask you veterans how you folks learn program in assembly and about computer architecture for the x86 family. In addition to finish learning C, I am also reading the book From bits to Gates to C and Beyond. In the book, it uses the mini LC3 assembly language. I also have books on assembly programming and computer architecture. The few famous ones i have are Computer Organization and...
What percentage of programmers have learned to touch type? Have you? Do you think it's important, not just for programming, but for more-than-casual computer users generally? ChatGPT didn't have much on it ("Research indicates that less than 20% of people can touch type fluently, with many relying on the hunt-and-peck method for typing ."). 'Hunt-and-peck method' made me smile. It added, "For programmers, touch typing is a valuable skill that can enhance speed, accuracy, and focus. While...
I had a Microsoft Technical interview this past Friday, the question I was asked was this : How do you find the middle value for a dataset that is too big to fit in RAM? I was not able to figure this out during the interview, but I have been look in this all weekend and I read something online that said it can be done at O(N) using something called the counting sort histogram algorithm ( I did not learn that in my advanced data structures and algorithms class). I have watched some youtube...
