The RAM required increases more slowly than linearly.
You should be able to cope with a lot more lines than that unless another
process is already using all the RAM. What OS are you on? You could use top
(Unix) or the Task Manager (Windows NT) to examine the memory being used.
Another thought. Have you got a lot of different filenames (for example, if
they're dynamically generated?). If so, maybe you need FILELOWMEM instead of
HOSTLOWMEM.
