does not handle "

Need to handle illegal integers, e.g. var a:=5a

It is throwing errors on situations that arrise due to uncorrected
errors from previous projects. For example, the case on the
typechecker project, where your typechecker is throwing incorrects
"type not defined errors" in cases like "if(10>5)"

The ending position of the string is used as the starting position.

The following is a simple tiger program

"string"

The output should be

STRING(string)     2
EOF   10

instead of

STRING(string)     9
EOF   10

The parenthesis does not close.

"I have also found a bug in the for loop in your translate module
(part of IR/Frame project) that I didn't report to you earlier. The
for loop is jumping to an incorrect label such that the conditions are
not being tested."

How are you handling cases where types have the same name as
variables? Should it return an error?

Need to handle recursive declarations: At the moment not throwing
errors. (See page 120)

Afterwards, check also recursive and mutually recursive functions. It
seems there is also a labeling error. At the moment they are throwing
uncaught exception errors

• Certain expressions should not return any value at all (see page
  516). For example a:=(if (5>4) then 3) should return an error

• For "if then else" expressions the types of "then" and "else" values
  must be the same

test case 27

If, while, ... expressions are returning errors when not supposed to,
e.g. "if(5>3)..." returns integer required error.
