There is no AppleScript word or property called “OPERATORS”. Lef has defined a string with that variable name and then chosen one character from the string at random in the repeat loop. He could have done the same with a list: set OPERATORS to {“+”, “-”, “*”}, but that’s a lot more typing than the string he used.
The clever bit of his script is that he builds a new string: (a as text) & o & b and then runs it as a script fragment: set r to run script text_fragment_here. You can make a list like that too:
set list_string to "1, 2, 3, 4"
set L to run script "{" & list_string & "}"
L --> {1, 2, 3, 4}
Square brackets (‘[’ and ‘]’) are used in AppleScript to represent a certain kind of list which hasn’t been supported for over thirteen years (ie. since before I started!). They shouldn’t be used in place of parentheses ” or at all.
