Executing code based on a condition can be performed using if and if / else statements.

If Statement Syntax (den = Data Export NameVarCode = a StudyTRAX Variable's Code)

if (#den1 #VarCode1 == 0) {
   #den2    #VarCode2 = 1;
   Other statements here...
}

If - Else Statement Syntax (den = Data Export NameVarCode = a StudyTRAX Variable's Code)

if (#den1 #VarCode1 == 0) {
   #den2    #VarCode2 = 1;
} else if (#den1 #VarCode1 == 1) {
   #den2    #VarCode2 = 2;
} else if (#den1 #VarCode1 == 2) {
   #den2    #VarCode2 = 3;
} else {
   #den2    #VarCode2 = 0;
}

Functions are defined on the "Variable Dependencies" tab (see image). The standard way to set up functions is:

1. In the "Expressions" box type the text "main()"
2. In the "User Defined Functions" box type the text "function main()" and then type out the function
3. Don't include the quotes from the text main() and function main() above
