What's faster memory or sequences?
`````````````````````````````````````````````````````````````````````
I am working with virtual screens and sprites, and i want to know
which is faster?
Like this:
Clearing a sequence with repeat (0,length(sequence) )
OR
Clearing memory with mem_set(loc, 0, length)
Poking a whole sequence to the video memory
OR
Memcopying an allocated memory block to the video memory
Subslicing a one-dimensional sequence
OR
Use random acces in a 2D- sequence
OR
Subslicing memory by calculating the section
Thanx

In general, memory is always faster.

Dunno on that one..haven't tried all of them, however, slicing memory by
calculation is fast. Would be faster if we had bit shifting (for
calculation of offsets and such)
