D52 version 3.3.4 is now available from the link on the left side of 8052.com labeled 'disassembler'. This version includes several bug fixes, a new command line option, a new control file directive, and an early version of a code analyzer for Z80 processors.

The new -u command line option will tell D52 to output mnemonics, labels, symbols, etc in upper case for cross-assemblers that may require it. Comments in the output stream are not affected.

The new 'p' (for patch) control file directive is similar to the comment directive, except that the user supplied string(s) will be output as code, not comments. Might be useful for adding macros or pseudo-ops to the disassembly output file.

Please send bug reports to me at the email address given in the documentation. To avoid having your email eaten by my anti-spam software, please put "D52" somewhere in the subject line.

Cheers,
Jeff
