QuickBASIC String Descriptor Has Six Bytes: 3.00 Has Five (37313)
This article was previously published under Q37313
SUMMARY
The length of a string descriptor in Macintosh QuickBASIC is six
bytes, in both compiled and interpreted programs.
Note that the Microsoft BASIC Interpreter Versions 2.00, 2.10, and 3.00
uses a five-byte string descriptor. QuickBASIC has changed the length
of its string descriptors from five bytes to six bytes so programs
written in the Microsoft BASIC Interpreter environment can be more
compatible with the compiler. The Microsoft BASIC Compiler Version
1.00 (released before QuickBASIC) also uses a six-byte string
descriptor.
An assembly-language routine that uses string descriptors and used to
work correctly with the Microsoft BASIC Interpreter Versions 2.00,
2.10, or 3.00 may now give strange results in QuickBASIC. The
assembly-language routine will need to be rewritten to take into
account the larger string descriptor size.
