Creating variables

The following structure can be used to create variables in the script editor:

SET | LET variableName = variable value ;

The following lines are examples of a variable definition using SET:

SET vMyString = 'This is a string';SET vAnotherString = today();

When using SET, any value to the right of the equals sign will be treated as a string.

The variables vMyString and vAnotherString contain strings even if the second line has a form of function inside.

If you want a variable to hold the result of a function after it is evaluated, use LET:

LET vToday = today();

In this example, vToday will hold today's value returned by the function today() instead of the string 'today()'.
