With "TIC=TICKS()" you get the result of the test "TIC equal TICKS()" which in your case in false (zero).
With "TIC:=TICKS()" you assign the value of TICKS() to the the variable TIC, it's the same as with the Sto command "TICKS()▶TIC" where you store the value to TICKS() into the TIC variable.

So in your original program you were comparing TIC to TICKS(), then TIC to TIC/1000 but never assigning a value to TIC, so the default value (zero) assigned to TIC at its creation by the "LOCAL TIC;" statement was printed.

Thanks again Didier !....I'm sure with other devices I've used, if you want to comparison test you would enter '==' !, no wonder It confused me
