Checking Memory Usage
-
™
&
When all memory is cleared and all defaults are set, the
standard TI
-
86 has
98,224
bytes of available random-access
memory (RAM). As you store information to RAM, you can
monitor memory allocation on the Check RAM screen.
MEM
FREE
reports the total number of bytes available in
RAM. Conversely, all other numbers on the screen report
the number of bytes that each data type currently occupies. For example, if you were to
store a 50-byte matrix in memory, the
MATR
total would increase to
50
bytes, while the
MEM
FREE
total would decrease by 50 to
98174
bytes.
To display the number of bytes that a specific variable occupies, display the
DELETE
screen
for that data type (page 231). Scroll the screen, if necessary.
For information on
TOL
(the
tolerance editor), refer to the
Appendix.
