CBM prg Studio Version 2.5.3 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:

• New source conversion tool to convert Develop64 files to asm format.
• New tutorial explaining how to use projects to manage assembly source files.

Bugs fixed:

• Relative addressing with offset, e.g. BMI *+4.
• Some invalid relative offsets not detected.
• Excluding source files from a project.
• Removing source files from a project.
• Assigning a variable to another variable.
• Warnings if invalid BASIC jump (goto, gosub etc.) destinations are detected.
• Unknown labels not detected.
• Screen designer not retaining ‘reverse off’ after new line.
• Forward-referenced cheap labels not working.
• Duplicate cheap labels not detected.
• Some UI issues.
