[fpc-pascal] hello world
Folks:
Apologies for the beginner nature of this query...
why won't this compile? It is the only open file and is saved, looks
like a main program to me.
program Hello;
begin
writeln ('Hello, world.');
readln
end.
getting:
No main program found in open files. Can not build.
thanks!

Re: [fpc-pascal] readonly variables

It happens to be so most of the time, but your code should never assume this is so, except for global Ansistring variables. If all globals weren't initialized to 0 a lot of code from lots of people would potentially be in trouble. I've been using Pascal/Delphi for a very long time. Trust me I know my stuff. For what its Wirth None of our code ass-u-me-s (nor requires) initialization of _our_ globals (or locals) by any compiler or OS; all of our globals and locals are specifically initialized. Helps us survive the shifting Macintosh pascal compiler scene with 1988 source code. Before that I used Pascal at Honeywell, 1978-1988; all variables were initialized by their programs, not the OS, not the compiler.

It's the first 2 bytes of a file, which contains the magic number of the file.

Re: [fpc-pascal] Install FPC/Lazarus for Win CE
I for one can not get Lazarus to run on 10.4.11 G5 Quad. Followed all installation instructions - no launch. I don't care to download the source and compile, I expect the easy installation to work (funny Mac user). I'll wait for the dmg release. Xcode seems to host FPC OK.

Appearantly, I'm not the only one, I've seen problems with it on the mac-pascal list too. On Mac OS X 10.5, I can't start Lazarus (OS-error : You can't start lazzarus.app - it's not supported by this architecture) That's the reason I want to know exactly what steps to perform before I start.

Trivial of little value or importance : huge fines were imposed for trivial offenses | trivial details. • (of a person) concerned only with trifling or unimportant things. Ass-u-me-s you have svn... and unless I read the lazarus page wrong the FPC source is required, yes? The more I use FPC Xcode, the more trivial Lazarus becomes.

Re: [fpc-pascal] Re: classes initialization
p.s. I think the inconsistent behavior between local scope records and global scope records is kind of a flaw/danger in modern pascal.. as the bugs may not be caught until someone builds a program with local scope var.. Using uninitialised variables is virtually always bad, regardless of the scope. And the fact that global variables are zeroed at the program start is afaik not defined by the Pascal standard. It's just a side effect of the way most operating systems work. Affirmative. Pascal does not define any variable initialization itself - one should always init all Pascal vars of any type. Doing so is an excellent coding habit also portable to any other language/OS - protects against low-level implementation changes. I never trust a side effect I didn't code myself. 8-)) Gary ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] update confusion...
Folks, Not sure where to ask this, so I am starting with this list... Upgraded from xcode 2.1 to 2.4 and FPC 2.2.1. G5 quad, 10.4.11. My FPC xcode project builds ok, but, when I add an empty file and close the project, xcode says, to the effect: The project myProject.xcodeproj is read only You may need to SCM edit the project to gain writability. We don't use SCM, the SCM menu enable SCM is not checked, the SCM system is None, the project file is not locked, has read/write access for all permissions. Prior XCodes/FPCs/Templates had no problem.. Any help? Gary ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
