Comments

The current two-byte token identifiers are t2ByteTok, tVarStrng, tGFormat, gVarSys, tVarOut, tVarGBD, tVarEqu, tVarLst, and tVarMat, and on the TI84s, $EF.

TI has updated the OS for the TI84s to return true for $EF, the identifer for the TI84s new tokens. It would be nice if someone would run this program to check to see how OS 1.19 reacts to $EF. (Source)
