Re: Memory fragmentation?
Memory fragmentation never occurs on the TI-8x calculators. (I don't know
about the TI-92). When variables are deleted, everything else in memory is
moved back to fill the empty space. With only 32K, this doesn't take very
long. This is one reason that the calculator is slower when memory is more
full; more data has to be moved when a variable changes size.

Subject: Memory fragmentation?
Ok, I was just wondering... Does memory usage on the TI-8x caculators ever
become fragmented, like how a hard drive would? Like, if I had 300 bytes
free, then wrote programs A,B, and C, each 100 bytes in length. Then i
deleted programs A and C, and wrote a 200 byte program, D. Would this
program D span two separate blocks of memory? if it doesn't, why not, andif
it is a normal/routine occurence, how does the calculator know where to read
to next?
