Thanks Rob, I haven't. Something to think about for a future version.

BTW, I've managed to run the remarkable program you recently posted for computing the digits of pi:

Code:


1 unsigned long a=10000,d;
2 unsigned b,c,e,*f,g;
3 main(){
4  printf("digits?");scanf("%u",&c);
5  c=7*c/2;c-=c%14;f=malloc(4*c+4);
6  for(;b-c;)f[b++]=a/5;
7  for(;d=0,g=c*2;c-=14,printf("%.4lu",e+d/a),e=d%a)
8   for(b=c;d+=f[b]*a,f[b]=d%--g,d/=g--,--b;d*=b);
9 }

It is interesting to compare the lengths of the C code and the translated bytecode, 15 lines vs 101:






I'll now add some display functions to the language in order to display the digits as the program runs.
