QModeKey |
Function (ROM Call 0x182) |
Checks whether argument is code of a mode key.
QModeKey returns TRUE if code is code of a mode key,
else returns FALSE. It assumes that code is
code as the function ngetchx for reading the keyboard
returns. Mode keys are keys which may cause change of the current application or
the configuration of the calculator. The following keys are mode keys on the TI-89:
HOME, APPS, MODE, VAR-LINK, SWITCH (2nd+APPS), MEM, QUIT, Y=, WINDOW, GRAPH,
TblSet, TABLE and OFF (codes 277, 265, 266, 4141, 4361, 4150, 4360, 16652, 16653,
16654, 16655, 16656 and 4363). Note that codes returned by
ngetchx are mostly equal like codes returned by
BASIC command GetKey, but codes of arrow keys, and keys pressed together with
Diamond keys are different. See ngetchx for more info.
