Stephen Williams c49b21115a Handle strings as class object properties. 
While we are at it, fix a handling of null strings in
string expressions.

Stephen Williams 074055bc58 Implement static arrays of strings. 
This means extending the vvp to add .array/str objects and
include instructions to access the array. Also add the parser
and code generator support.

Stephen Williams d6726f62fc Implement substring method for string expressions. 2013-01-05 11:40:12 -08:00
Stephen Williams 0059fb1ec7 Support for dynamic arrays of strings. 
Strings, when put into dynamic arrays, are treated as first class
types much line reals. Add the code generator and vvp support for
this situation. Also fix a bug distinguishing between character
selects from strings and select form arrays of strings.

Stephen Williams dc39714d65 Support string literal strings in the vvp runtime. 
This also advances support for string expressions in general.
Handle assignments to string variables in the code generator by
trying to calculate a string expression. This involves the new
string object thread details.
