does not work any more

[ghost]

I tested the functions today, but they do not work anymore. ;-(

Checked it with the original TI Student Software and two calculators, a CX II-T and a CX II-T CAS.
I used the simple expression
eval_expr("sqrt(90)",True) - that one from your example. (Tested False or no second param also)
On the CAS I get: line 38, in eval_expr
TypeError: Invalid number format
That is the line: res = readST("tmppy_") # retrieve stored value

On the non-CAS I get: py", line 37, in eval_expr
TypeError: Variable storage failed
And thats the line: writeST("tmppy_", 'strsub(string('+str(expr)+'),"/","$%$")') # eval and store

Calculator-Software: 5.3.0.564 on both calculators.

Any chance to fix the problem, or has evil TI blocked that method?
