Dear List- I have an integer variable which is to be user assigned in an interface during runtime. I want my program to check if that value is left blank/null.
Using an If...Then statement, how do I tell MapInfo to identify that the variable is empty? I can't use zero for the check obviously, but is there a MapBasic code that identifies a null value? Thanks!!
