Working with text in PV-WAVE is equivalent to working with strings. A string is a sequence of 0 to 32,767 characters. Strings have dynamic length (they grow or shrink to fit), and there is no need to declare the maximum length of a string prior to using it. As with any data type, string arrays can be created to hold more than a single string. In this case, the length of each individual string in the array depends only on its own length, and is not affected by the lengths of the other string elements.
