The example below shows how to estimate memory usage. Every message
programmed has 14 bytes of overhead. Also, every space, control T, control
V, and control X also use one byte.
Example: DL20 contains 475 messages with an average length of 35
characters.

(475 x 14) + (475 x 35) = 23,275
Overhead + Message Text= Approximate Total
The Historical Events Stack uses a maximum of 3000 bytes of unused
memory. If the Historical Event Stack is used in your application, enough
non-message memory space should be allocated.
