Hello there,
I've almost arrived at my goal!
I've almost arrived at my goal! But; I don't know how I should continue. I will send you two files. They're created with Uiflow 2.0. The first version, named Prova_basica_1 is absolutely functional, and the second one, named Prova_basica_2, is my nightmare!
The trouble finds in the conversion from ASCII code to character, I can't do it
Please, may you aid me?
Thank you, and excuse me for the inconveniences.
Best regards!
P.S. In this message I send you two images from UiFlow 2.0 program and I've just attached below the code from two programs
Code Prova_basica_1:
