Strange problem with FPC 3.0.2
« on: April 03, 2017, 03:43:47 am »
I installed the 3.0.2 version of the free pascal compiler on my desktop(Windows 10-x64), there was a very strange question: when testing the console program, I entered a number in the console and press Enter, the cursor jumped back to the beginning of the line and didn't wrap to the next line, Ctrl+C break function didn't work too. please help ...

I just tested the 3.0.2 fp.exe from the official distribution on windows 10.1 64 and it works fine. That version is a 32 bit executable one of course.
To stop the ide you do not use ctrl-c but alt-x by the way. ctrl-c is intentionally intercepted.

Thanks, I also tested version 3.0.0 and had the same results on my desktop, It seems "Enter" didn't wrap to new line in console program and Ctrl-C resulted "^C". But it does work fine on my laptop which is also window 10 x64.  :'(

I found that someone on the Internet had the same problem, but there was no solution.

I also built a 64 bit version. Same thing: everything works as expected on windows 10.1 64 bit.
Try re-downloading and re-installing FPC and use only an official installer from here http://www.freepascal.org/download.var

If you found something on the internet and it is NOT on this forum, plz provide a link: there's lots of bogus info around and you will find many experts - if not all - only here.

I tried all the installation again according to your suggestions, unfortunately didn't work it out. Free pascal works fine except the Enter-wrap problem while debuging console program. Is it possible windows configuration caused this?
The following is the same problem searched from web, sorry for the language

Hello!
I also have windows 10-x64 and the same thing happened to me. When I used the 'Run' option or when using the 'Debugger' with the 'Step Over' (F8), the console appeared, and when I had to type some number or character and pressed enter, the cursor was down and I received erroneous results.
What I did to fix it was, add the 'Clrscr' command, which cleans the console.
I am going  to attach the command line and how the console would look.
Hope it works for you, regards!

thank you, enzo740! Your solution is works fine! The main thing is "uses crt" clause, in my case "clrscr" itself is not nesessary. I use "uses crt" in my program and this fixed the problem

Why are you using Write and not Writeln? i'm curious.

To have the cursor wait for input directly after the colon ? (with a writeln it would appear on the next line).

ohh, great! you're welcome!  :D
Edit: I tried what you mentioned and it's true! It is not necessary to use the 'ClrScr'. Only with the 'Uses CRT' works! Thanks!

In effect, it is to keep the cursor on the same line. In general I use 'writeln', but if after a text there is an input, I use 'write'. It's purely aesthetic, my programming teacher taught it to me  :)
