Hi,
I am new in TLA+ and in learning TLC, there are material related to the language but can you share any guideline that also tells how to use TLC and write a code in it. I have wasted so many time just to write a single specification but continuously finding errors. I have logic but syntax and writing spec is so difficult in TLC that i have no other option to say please provide me some good material. following is the error I am facing i dont know what is going wrong.
