Overview of Strings
An IDL string is a sequence of characters from 0 to 2147483647 (2.1 GB) characters in length. 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.
Note
This chapter covers operations on strings. For information about using the ` and "characters to create valid strings, see String Constants.
