Strings, due to their potentially large size, are stored outside of a routine's code section, in the data section. To access the correct string, you must read the jump index, then the real address from the jump table - and extra layer of indirection will result in more flexible data down the road, I hope. Other changes include: * Added string concat operator .. * Added TOY_STRING_MAX_LENGTH * Strings can't be created or concatenated longer than the max length * The parser will display a warning if the bucket is too small for a string at max length, but it will continue * Added TOY_BUCKET_IDEAL to correspend with max string length * The bucket now allocates an address that is 4-byte aligned * Fixed missing entries in the parser rule table * Corrected some failing TOY_BITNESS tests
