Hi
I have always been curious-but really never had to see this in this way.
I am currently updating a system which has never been compiled-not with a view
to compiling but to clear up syntax errors. So i started with some number of
errors(somewhat north of 100)…i cleared some stuff..and then s

Yep thats pretty much what i am figuring..but I was just curious if anyone know
what the 'trigger points’ that cause it to give up are-if we knew what they
were we could clear up those errors first(I have been at this one all day today
and most of yesterday)

If it was closer to the days when i wrote load of errors i might have worked
out(but then i was so daft i could not have worked it out)..now that i am
clever enough to work it out i don’t need to work it out because i don't write
100s of errors
…end of a long day clearing 100*n errors ge

Oh that this was V15!!!..its not a complaint about the compiler its doing a a

Nigel,
The Compiler changed some versions back and no longer detects all error sin
one pass...at least in certain situations. A few tips and things to look
out for:
* If you've got a missing method, the Compiler usually stops reporting
errors, even if there are multiple cases of the problem.

Thanks for the insight. I think i might try that-day 2 and half already of
this! Hopefully the compile with ‘all vars are declared should show me what is
not declared(!)…i would love to be able to run my code(which i spoke about on
here) that now auto sets the declarations of variables at
Nigel:
A couple of thoughts on this…
I couldn't find this documented but 4D's compiler does three "passes"
through the source code (when you're not typing all of your variables).
IIRC, the compiler displays what it's doing for each pass but newer
versions of 4D + modern hardware are so fast that
$2, etc and types them. If
you are doing the typing then it gets this info from “Compiler…” methods.
Then you have local variables to deal with. Could be it builds this typing list
when it is scanning all the methods. Could be during all this typing scanning
it does some syntax checking along the wa

Tim,
That's probably an inflation-adjusted number. Which makes the first 128k

Yes that is kind of what i thought and can remember the old days so would kind

Not copyable is not exactly true ;)

anywhere you may use:
- Execute Formula
- other means of indirect code execution. Method(s), code stored in
data for example

You really should try to fix those...That is 69,000 places that 4D is guessing
what the variable type should be - instead of you explicitly telling 4D what

This is where strict variable nomenclature with typing info helps a lot.
You can easily create a method that can gather all locals in a piece of code,
and add the declarations at the top of a method.
You can even apply that automatically using METHOD GET CODE and METHOD SET CODE.
OTOH if you have
ariable at the top of that
method then compile again then the 69,000 would be reduced by 100. So don't let
the 69,000 errors scare you, it may be much less!
The 4D compiler is trying to warn you about coding mistakes, it is better to
fix those coding mistakes rather than ignore them.

Nigel,
I went through a similar process several years ago when I changed the
compile settings on a rather extensive database to 'all variables are
typed.' I forget the number but it was a lot. Daunting.
I forget how much time I spent on it but it turned out to be much less than
I thought it would
Heinz, Timothy.
I completely agree. A strict nomenclature with typing is essential.
In fact its the only way i too have been able to implement auto declaration in
my code-not just locals-i was inspired by your comment about doing it for
locals on here a while back to go back and complete work
