it's after an if statement and before an else so it doesn't need a semicolon?

I suspect the output when writing to StdOut is moving the cursor to a location
that is not known or kept track of by regular writeln in the CRT unit. If this
is what's causing seemingly random positioning, You could possibly keep track
of where the cursor is supposed to be yourself with the

If it shall be a quiet NaN doesn't that mean it would never cause the

Quoting James Richters :

No, that’s not normal, it's not supposed to give you a runtime error.
Anything that results in an answer that is Not a Number is supposed to be set
to NaN, not give you a runtime error 217 and terminate.
Infinity minus itself is undefined and therefore Not a Number and should be set
to NaN, but

I am trying to figure out how I can remove the last line of a text file to
replace it with a new one. I can do this with typed files with seek... but I
am confused on how I could do this with just a text file.
If I use:
Var Myfile: Text;
Mydata:String;
Thank you for the advice and for the example. I don't know what is considered a
large file.. these files can be maybe about 1000 lines long, most will be less,
would this solution be suitable for files of this size?
Is Tstringlist something like an array of strings?
-Original Message-
I have a whole section of diagnostic writeln's in a program, and it's tedious
to comment them all out/in as needed. I'm curious if doing something like
Const
diagnosticdetail=false;
If diagnosticdetail then Writeln('diagnostic info');
Is the same as
// Writeln('diagnostic info');
And

I also prefer ‘console’ but I prefer it for heavy graphical UI applications as

Is there a copyfile for Freepascal I can use without installing Lazarus?
I found:
http://wiki.freepascal.org/CopyFile
but that seems to only work with Lazarus.
I just want to make a copy of a file into a different directory and maintain
it's timestamps etc
Any suggestions?
James
How would I use this LazUtils Package with just FPC? Is there way to download
it by itself? Or would I have to Install Lazarus somewhere, go find the unit
and copy it in with all my FPC Units?
I was hoping to do this without doing something like that because then every
time I install a new
