Out of string space
There is too little available memory for string storage, either at compile time or at run time.
If your program includes many strings, or very long strings, either eliminate some strings, or restructure your program to limit the set of strings that must be kept in memory at any one time.
If your program includes a great many names, you may need to restructure it similarly. LotusScript® creates and stores a string for each name. The string's length is the number of characters in the name. For example, if your program includes a definition of a type with several thousand members, string storage space may be exhausted.
