Of course ..you can  :)

Well...the most known is old Aurel Basic written in EB by IonicWind.
Then .. experimental Ruben Interpreter written in Oxygen Basic    .
Then.. failed attempt to bytecode toy interpreter ...i am too lazy for that  ::)
Then... JimKlutho basic written in PowerBasic ...translation to Oxygen Basic..
Then newest - token based interpreter micro(A) ...he he

also
Aurel Edit - code editor written completely in Oxygen Basic with pure winApi.
awinh.inc - include written in Oxygen basic for Oxygen Basic GUI apps.
etc..
etc..

Let say ..easy with a little help of Charles of course.
Look BASIC is BASIC and syntax is very similar.
so i do  it function by function and made it  :)

ScriptBasic allows GOTO / GOSUB within a function / sub and even using duplicate labels defined in other functions. You can't jump in or out of a function/sub with GOTO.

 Charles... i apologize for bringing this back, but, is there a way to add a more free goto? It doesnt
matter if its a lower level method... maybe i can take a look at oxygen's code...

 I am trying to re-implement exit macro, it works but by adding tricks that not always will work
depending on the content of the macro.

 Sometimes the macro can end where a block starts... so, emulating an EXIT MACRO will fail, because
exiting the macro would force jumping into a block like do/loop.

 Scopes are great, but sometimes skills are crippled by them...

Hi Brian,

The linker requires that 'global' labels get special handling so they are not disallocated when blocks close.

I'm testing a scheme in which global label names start with a dot:

Code: [Select]
'15:45 16/05/2019
'jumping into inner block
goto .gl
'jmp fwd .gl
(
  print "!"
  ..gl 'global label
)
print "label location " @.gl

 That is good news Charles!! This was driving me crazy!
Please let me know how it goes! :D

And... sorry to be a pain in the butt! :(

 I enhanced macros quite a lot, i promise this is going to be worth it. You will see soon!
