Hello,

i want to use in a LUA script xpcall(). Does anyone know how? Can i use any function which i have created with the program editor?

Thank you in advance.

Hi,

Why would you use xpcall instead of pcall since on TI-Nspire the "debug" package is not available ?
Anyway, just google-it

I don't understand your question (maybe because its answer is obvious) I'm just looking forward finding a deeper problem : do you have any source code ?

blauemauritius:
thank you. I will see what is written in your links.

I will give you a feedback.

blauemauritius:
thank you... Is the call and the structure in LUA for NSpire the same?

Do you have a short example?

Yes, the same. TI did not reinvented the Lua, they only turned it event-based and added their API.

The example given in the second link will work

--- Code: --- local status, err = pcall(function () a = 'a'+1 end)
print(err)     --> stdin:1: attempt to perform arithmetic on a string value

local status, err = pcall(function () error("my error") end)
print(err)     --> stdin:1: my error

--- End code ---
