  I'm not sure what variants of Pascal you are used to, but for the ones I'm
used to, you can only declare new variables at the top of code block, not
anywhere in the code.

Strictly speaking, you are correct: global variables in Pascal must be declared near the beginning of a file.
But local variables declared inside implementation section of (rather long) pascal unit do smell like globals to me: their scope covers almost whole file.
And I incorrectly call them "globals".
They're exact counterparts of Dirk's "semi-global variables".
