string like arrays

[Marco Antonio Abreu <falecomigo@...>]

Hi,

there is some how, in Lua, to access string bytes like an array; 
something like what we can use in C or Pascal?

examples:

s = 'Lua race'
print( a[5] ) --> prints "r"

It would be very desirable to be able to write too, like:

s[5] = 'f'
print( s ) --> prints "Lua face"

Thanks,
