CBM prg Studio Version 3.9.0 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.

CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

• Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
• Tabbed MDI.
• Syntax highlighting.

What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.

New features in v3.9.0:

• Assembler:
  • TARGET directive.
  • Logical operators with ‘ifdef’.
  • Complex expressions for constants.
• Debugger:
  • Pass label names to debugger.
• Screen Editor:
  • Show ECM register in status bar.
• Sprite Editor:
  • Easier navigation.
• Character Editor:
  • Change scratchpad background colour.
  • Easier navigation.
• General:
  • Command window.
  • Autolaunch prg name is per project.
  • Import SEQ files.
  • Force rebuild of source.
• BASIC:
  • Abbreviated commands for BASIC 3.5.
  • Removed spaces on code generation.
  • Force rebuild of source.

Bugs Fixed:

• Screen Editor:
  • ECM tools (re-colour, box, text).
• Assembler:
  • Some character translation issues (‘[', ']‘, ‘_’) etc.
• BASIC:
  • Fixed quoted and DATA strings for basic 3.5.
  • Renumbering certain ‘ON…’ lines.
  • Reformatting code.
  • Syntax highlighting for BASIC 3.5
  • Much faster code generation
  • Some incorrect tokens for BASIC 7+

See the help for a complete list of new features and fixed bugs.

Note In this version, each target machine can have its own default project directory. If you are upgrading from a previous version (before version 2.5.1) of CBM prg Studio you may be asked to set up your project directories again. Your current projects will not be affected.
