EEX Problem with CAS Programs

[Helge Gabert]

Drove me nuts:

My CAS program wouldn't compile for some reason; I checked all the lines of code, re-checked, still didn't work. Only after isolating each expression, I became clear that
in "1E-3", "E" apparently cannot be typed in with the EEX key.

Instead, the user needs to erase the funny looking "E" (from EEX) and replace it in the program with the "E" from the letter keys. Unbelievable.

(This is not a problem with non-CAS programs).
