Caption := ‘Number is NEGATIVE!’;

You may think it looks better, but it can’t compile as the semicolon refers to the *outermost* IF statement, so the second ELSE clause is now illegal.
better to use:
if (…) then
if (…) then (…)
else begin end
else (…);
Wathch for the begin-end pair without any contents!
Another option is to use one begin-end pair without contents:
if (…) then
if (…) then (…)
else begin end
else (…);
It should be this.
if (j >= 0)
then begin
if (j = 100)
then Caption := ‘Number is 100!’;
end
else Caption := ‘Number is NEGATIVE!’;
The above code is not showing my indentation. The second If Then End should line up with the first Begin
Hoping one day all block statements in a language will have a simple end mechanic without having to begin/end or squiggly:
if x > 0 then
blah;
blah;
else
foo;
foo;
end;
