Hello,

like the topic says:

a give construct should be interpret through a single pass???:

IF 2 == 3
   print "not print"

   IF 2 == 3
     print "not"
   ELSE
     print "wrong1"
   ENDIF

   print "3"

ELSE

   print "this"

ENDIF


Thanks for helping
Jens
[My usual advice is to translate the source to something easy to
interpret like an AST, then run your interpreter on that.  Trying
to jump around in the source code and remember when to parse what
and to avoid side effects when parsing through code you're supposed
to skip is miserable. -John]
