[SOLVED]"Unit expected but Program found!?" Whats wrong?

[coradi]

Program xyz;
 Begin
end.


this works BUT

Program xyz;
Uses crt;
 Begin
end.

not?!
Unit expected but Program found!?

All my old Programs doesn't work to..the same failure message?

[RayoGlauco]

For me, it compiles ok, as a "simple program" project.
Lazarus 2.0.4, Windows 8

[coradi]

There seems a  big problem?!

If I compile it in freepascal folder..it seems to wordk..If i say
save to.c:\Tools\Pascal\test.pas

Then it says..the message with the Unit!??!
BUT!!!
If i then say ok..then save it in an other order.then I only get a windows..to save the Listbox.txt!??!?!?!?
It isn't possible then to save the .pas file anymore.
If I THEN try to read an old pas file an try to compile it.I got th same failure message?!
If i close FPC and open it again and try to compile an old project it works fine..till i try to copmpile it like before..then error Message again..and then nothing will compile anymore

[coradi]

Why isn't allowed the
 Program Windows;

If I do this , this happens


If i reanem Windows in xyz, it works

[MarkMLl]

What happens if you try to compile your file using the fpc compiler invoked at the command line?

[glorfin]

(1) Try saving your program to a file with the name equal to the program name (program test in test.pas). Not quite sure, but I think it may help.
(2) There is unti Windows in fpc, which is probably used by default, and this makes your unit or program Windows impossible.

Regards!

[coradi]

Yes, but My is names Windows1 not Windows

[coradi]

What happens if you try to compile your file using the fpc compiler invoked at the command line?

MarkMLl

Oh...with Turbo PAscal / I know how I do that..but there is no TPC or TP.exe...
How I do hat?

[MarkMLl]

Use the fpc command, like I said. I'd have expected that to have been put on the system path.

[coradi]

exactly the same


but why he comile both?!?
I wrote fpc sdfs.pas

and got this error Message and none of both are compiled
I already tried a Reboot and a new Install and a erlier FPC Version

[Handoko]

Maybe you need to run a scandisk or chkdsk c: /f
I know some disk issues may make PC works weirdly.

Have you try to install and run Lazarus to see if it works correctly?

On the post #9, the picture shows the file name is windows.pas. You should rename it because it may conflict with the unit windows.

[coradi]

I will try it later on an other Laptop

[Thaddy]

It is really simple: the program declaration must *exactly* match the program filename on disk. (or omitted altogether) and in the same case including extension.

Code: Pascal  [Select][+][-]

1. {$mode objfpc}
2. program test;  // on disk must be test.pp or test.pas or test.lpr NOT tesT or Test or test.PAS or Tset.Pas
3. begin
4. end.

Omitting program altogether is also valid:

Code: Pascal  [Select][+][-]

1. {$mode objfpc}
2. begin
3. end.

[Handoko]

If it is true, it should be documented. But I found no information that program declaration must exactly math the program filename:

https://wiki.freepascal.org/Program_Structure
https://www.tutorialspoint.com/pascal/pascal_program_structure.htm
https://tech-story.net/pascal-program-structures/

Delphi did mention it but it said only for application developed using CodeGear:

The program heading specifies a name for the executable program. It consists of the reserved word program, followed by a valid identifier, followed by a semicolon. For applications developed using CodeGear tools, the identifier must match the project source file name.

<this would be new for me too. No -i don't think so..but I wll try. Turbo Pascal don't need this.
Why should it?
