I expect the parser is told to expect something like
for EXPRESSION := EXPRESSION to EXPRESSION do STATEMENT
and then the Symbol table lookup is used to check if the first expression is a
valid loop variable... And expression will be something like
EXPRESSION
( EXPRESSION )
EXPRESSION
EXPRESSION + EXPRESSION
EXPRESSION
EXPRESSION - EXPRESSION
...
Since you started an expression with '(' it's looking for the closing ')' prior to
finding the ':='.. hence the error...
They should have specified
for IDENTIFIER := EXPRESSION to EXPRESSION
since all loop iterators have to be local variables (you can't use an array element or
dereferenced pointer can you?)...
