83Plus:OS:Variable Versions
From WikiTI
This page is to document the Version field in the TI-83 series calculator's Variable header.
Version Bytes
Here are the currently defined compatiblity levels for 83+/84+ programs and variables:
Default to 00h if no 63**, BB**, or EF** tokens are present.
| Number | OS Version | 63 range | BB range | EF range | Description |
| 00h | TI-83 (all) | 6300-6337 | BB00-BB67 | None | 'ZXscl' through 'ZXres' and 'npv(' through 'DiagnosticOff' |
| 01h | TI-83 Plus (all) | 6300-6337 | BB00-BBCE | None | Added 'Archive ' through 'GarbageCollect' |
| 02h | TI-83 Plus 1.15+ | 6300-6337 | BB00-BBDA | None | Added '~' through '%' |
| 03h | TI-83 Plus 1.16+ | 6300-6337 | BB00-BBF5 | None | Added '...' through inverse '=' |
| 04h | TI-84 Plus (all) | 6300-6337 | BB00-BBF5 | EF00-EF12 | Added 'setDate(' through 'ExecLib' |
| 05h | TI-84 Plus 2.30+ | 6300-6337 | BB00-BBF5 | EF00-EF16 | Added 'invT(' through 'Manual-Fit' |
| 06h | TI-84 Plus 2.53MP+ | 6300-6337 | BB00-BBF5 | EF00-EF3E | Added 'ZQuadrant1' through 'FRAC' |
| 07h | TI-84 Plus 2.55MP+ | 6300-6337 | BB00-BBF5 | EF00-EF40 | Added 'STATWIZARD ON' and 'STATWIZARD OFF' |
| 0Ah | TI-84 Plus CSE 4.0+ | 6300-63FF | BB00-BBF5 | EF00-EF75 | Added 'TraceStep' and 'BLUE' through 'Dot-Thin' |
| 0Bh | TI-84 Plus CE 5.0+ | 6300-63FF | BB00-BBF5 | EF00-EF7B | Added 'tinydot' through 'Asm84CEPrgm' |
| 0Bh | TI-84 Plus CE 5.2+ | 6300-63FF | BB00-BBF5 | EF00-EF98 | Added 'Quartiles Setting...' through 'eval(' |
| 0Ch | TI-84 Plus CE 5.3+ | 6300-63FF | BB00-BBF5 | EF00-EFA6 | Added 'Execute Program' through 'piecewise(' |
| FFh | None | 6300-63FF | BB00-BBFF | EF00-EFFF | Invalid tokens |
Ranges are inclusive.
Notes
63** token ranges are not considered by a calculator when it generates the version.
0Bh is used for all of TI-84 Plus CE OS 5.0 through 5.2, despite tokens being added between them.
Clock Tokens
In addition, bit 5 is set if any token using the RTC (EF00-EF10, 'setDate(' through 'ClockOn') is present. Presumably the intention was to allow some future 83+ OS to support the new tokens that don't require an RTC, but this never happened.
