Just as you can store numeric variables, you can store string variables, which contain text instead of numbers. Here is an example:
   word1$ = “Hello”
   word2$ = “world”
   sentence$ = word1$ + “ ” + word2$
   writeInfoLine: “The whole sentence is: ”, sentence$
Yes, this is another way to get the sentence Hello world into the Info window. It's a more linguistically valid way to do it, and here is how it works:
word1$, which is a string variable (as we can see because its name ends in a dollar sign).word2$.word1$ + “ ” + word2$, which contains two variables, namely word1$ and word2$.sentence$.The whole sentence is: Hello world© ppgb 20130411
