Actually, how big the executable is depends on the compiler.  I don't do C,
but, in other compilers this is the case.  For instance, Turbo BASIC would
produce a 47Kb executable of "hello world" because it links a library of
subroutines that for the most part won't be used.  ASIC, another BASIC
compiler, writes the same program in less than 100 bytes - basically the
string "hello world <CRLF>" and a BIOS call.

My point has been that it seems that it takes an awful lot of computer
resource to program an 8 bit microcomputer.  I was just wondering if there was
a reason for this.  It appears that the reason is the overhead needed for the
overblown operating systems on our newer computers.

(...) That is partly the compiler and partly the linker and partly the idiot that put it togeter. Personally, I would be leary of generating a direct BIOS call in the generated code, but then I would avoid BASIC anyway. Even putting the actual (...) (26 years ago, 31-Dec-98, to lugnet.robotics)

Simply enough, it DOESN'T take an awful lot of computer resource to program the RCX. You could write a very simple single target (h8) c compiler for it that would be quite small. However building a cross target binutils and egcs compiler for ANY (...) (26 years ago, 4-Jan-99, to lugnet.robotics)
