pascal and C equivilent

Hi would anyone know pascal and how to change a packed record
in to C.

Here is a sample: -

fct=(lit,opr,lod,sto,cal,int,jmp,jpc);

packed record
f: fct;
end

with i do (*if i is an integer -instruction- *)
case f of
lit : begin
(*the rest is just a case structure*)
.................

tried looking on the web there is nothing on there which makes sence.
not sure what this means above though.
the code i am trying to convert is from http://www.246.dk/pl0.html
if you look right at the bottom where it says writeln('Start PL/0');
that is what i am trying to convert, done most of it but just not sure on what this part is doing.

Some help would be very apreciated. thankyou

You can probably ignore the packed aspect, if you're not writing the record itself to the file.

After that, its

Code:

---

typedef enum {
  lit,
  opr,
  /* etc */
} op_t;
typedef struct {
  op_t  f;
  int l;
  int a;
} instruction_t;
