Thank you for your help. I have found my problem which was that I had removed the file extension altogether somehow, so it is not surprising that I was having problems.

Red face; thanks again.

Thanks fr your reply.

I am not using Plato right now but simply a DOS command line such as

FTN95 %1 /CHECK /UNDEF /INTL /LIST /DEBUG

Where %1 is something like 'routine.for'.

I then us ...

I have been using ‘.for’ for my FORTRAN source files (i.e. not ‘.f’). After a recent system crash, every time I try to compile a ‘.for’ file I now get the message that 'the .f file’ cannot be found. ...

That's it.

In editing files yesterday I inadvertently removed the include file that held all the declarations and common statements - and, more importantly, the 'implicit none'. So compilation see ...

The first line of code in my initial post delivered the two lines of comment that followed.

I have even tried the following 'program' with no declarations at all

READ(5,500) (VIEW(I, J, K ...

The definitions are as below

INTEGER IOS, I, J, II, JJ

CHARACTER VIEW(20, 20, 4)*40

The latter is in a common block and the integers are local variables.

Thanks for your comme ...

I have a problem with the following:

*** Non-writable expression in READ statement
*** Compilation abandoned

I can find no reference to e ...

Thank you for your response.

I will see what I can do working from your example. I think the flashing aspect is not a priority right now.

Thank you for your help.

Here is the body of a program that works to produce a character alternating from green to red. With SDBG stepping through gives the desired effect. Running the program (F6) just gives a bla ...

I am writing to the screen from DOS but not formally a 'DOS box'. Essentially I am doing what I had done in FTN77. As an example this is intended to provide an alternating green/red characte ...

I am doing some very simple text handling and want to have a choice of colours with the results put on screen. In FTN77, I used COUP@ and this still works with FTN95 although I cannot find any refere ...

Thank you for this comment. I can see that the actual file extension is not a vital matter for compilation /linking.

I am grateful for your help and pleased to be using Plato.

Thank you both for your comments.

At present my include files have the .CB extension and it would seem sensible to amend these to .ins at some point. But for the moment at least I know how to acce ...

Further to my queries earlier, I now have updated ftn95 to the current version and am using it without issue. I have also therefore an updated version of Plato which I am now using and have a ...

Paul

Many thanks for your help. I will await details on how to update.
