As a baseline, here is Script BASIC predefining an array with 1,000,000 elements initialize to zero and then it assigns the index as a value to each element.

Code: Script BASIC

1. ' Array Benchmarks
2.  
3. SPLITA STRING(1000000,"0") BY "" TO array
4. FOR idx = 0 TO 999999
5.   array[idx] = idx
6. NEXT
7. PRINT "Lower Array Bound ", LBOUND(array),"\n"
8. PRINT "Upper Array Bound ", UBOUND(array),"\n"
9. PRINT "Index 500,000 Value ", array[500000],"\n"
10.  

jrs@jrs-laptop:~/sb/examples/test$ time scriba arraybench.sb
Lower Array Bound 0
Upper Array Bound 999999
Index 500,000 Value 500000

This is an example of creating a second dimension of letters and numbers for a dynamically defined associative array.

Code: Script BASIC

1. SPLITA "A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z" BY "," TO letters
2. SPLITA "0,1,2,3,4,5,6,7,8,9" BY "," TO values
3. array{"alphabet"} = letters
4. array{"numbers"} = values
5. FOR i = 0 TO 25
6.   PRINT array{"alphabet"}[i]
7. NEXT
8. PRINTNL
9. FOR i = 0 TO 9
10.   PRINT array{"numbers"}[i]
11. NEXT
12. PRINTNL
13. PRINT UBOUND(array),"\n"
14. PRINT UBOUND(array{"alphabet"}),"\n"
15. PRINT UBOUND(array{"numbers"}),"\n"
16.  

jrs@jrs-laptop:~/sb/examples/test$ scriba arraymix.sb

Note: There were no programmers harmed in this demonstration by using line numbers, LET and  $ (string notation) optional SB syntax.

I'm not seeing much interest in a scripting front end for O2. I don't see EZGUI, Brian's BASIC or the external debugger project making any headway either.

At this point in the O2 development cycle, I'm just going to be happy with DLLC as a Windows only extension module.

I'm going to create a thread on AllBASIC showing the evolution of  BASIC from Dartmoth to VB6 using Script BASIC code examples.

I don't see EZGUI, Brian's BASIC or the external debugger project making any headway either.

Although o2debugger is functional I need some feedback to make it evolve or at least fix bugs.
So I'm waiting you John .... The others too ;-)

My next O2 related task is to clean up DLLC removing the the threaded IUP functionality. The main features of DLLC is the dynamic FFI, bstr / wide strings, C structures create / access and low level COM support.

I already have a cross platform threading extension module (SBT) and my IUP extension module allows multiple instances of the message loop to run in threads. COM/OLE automation is provided in a CallByName wrapper.

As much as I like O2 and Charles, I have a working BASIC project to facilitate and without others interest in contributing external solutions to O2, It seems to be a waste of my time. At my age, time utilization is at the top of my list.

O2 may run code faster but when the difference is under a second, I'm not willing to give up the ease of use and the unlimited functionality SB gives me.
