Its like you read my mind! You seem to know so much about this, like you wrote the
book in it or something. I think that you could do with some
pics to drive the message home a bit, but other than that,
this is magnificent blog. A great read. I'll certainly be
back.

On early microcomputers, with their limited memory and gradual processors, BASIC garbage collection might usually trigger apparently random, inexplicable pauses in the midst of program operation.
