Let’s say that for whatever reason I want to know if the calculator on which I’m running a program is in Normal, Sci, or Eng mode. I can do length(toString(10, which is 2 in Normal, 3 in Sci, and 4 in Eng. But let’s say that for whatever reason I want it to be compatible with pre-toString calculators. Is there any way to detect this without assembly?
No; only Func/Par/Pol/Seq, Real/either complex mode, Full/Horiz/G-T, and Stat Diagnostics are detectable in Ti-Basic during programming.
Well, both involve a particular mode setting causing the calculator itself to display an error.
Real/Complex: You'd put something like √(-1)→Y in a line; when its ran, you get a Nonreal Ans. error in Real mode and no error in the other modes.
Stat Diagnostics: Performing a regression calculation (QuadReg, LinReg, etc.) and calling r, r² or R²; all these variables would be undefined if stat diagnostics are off.

You can do 'Number to String' on earlier calcs in TI-BASIC: http://tibasicdev.wikidot.com/number-to-string
