goto/label

[Miki Miki]

Helo there,

I was wondering if anyone could help me how to implement a grammar rule for 
GOTO statement
and also how to allow the option that a label can be aded to any statement 
in the program.

Essentially program should be able to jump to the label specified after GOTO 
statement and execute
that part of code. see example.



if a = 1 then goto c; end;
b := a + 10
end;
c: write(a);

In this case, program should jump to  c label after raching goto statement 
and carry out the write command.

Thank You

Mark
