14.7. Graph Database
There are several differences between TI
-
92 graph databases and
TI-89 / TI-92 Plus graph databases which are noted below. TI
-
92 graph
databases can be sent to the TI-89 / TI-92 Plus but TI-89 / TI-92 Plus graph
databases cannot be sent to a TI
-
92. Once it is received by the
TI-89 / TI-92 Plus, a TI
-
92 graph database still has the TI
-
92 version number
(version=TV_TI_92 in the SYM_ENTRY structure for that variable in the symbol
table, see section
13.3 Managing Variables
), which allows it to be sent to
another TI
-
92 from the TI-89 / TI-92 Plus.
