27 rather ?
you have a common beginner error
"; before else"
the "if then else" instruction format in pascal is
if Condition then Instruction1 else Instruction2
no ; before else.
the logics is that is pascal ; is an instruction _separator_
not an instruction _terminator_
An instruction needs not to be terminated by ;
it can be terminated e.g. by the keyword "end"
or by the keyword "else" as in this case.

you need first to allocate memory by
in C also you can have surprises if you do not allocate memory.
there is a shortcut with constants
const a: pChar = 'a';
const a: pChar = 'foo';
which makes both memory allocation and filling
but this is not allowed with --standard-pascal
which is very picky.
