CBM prg Studio Version 2.6.0 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:

• Assembler overhaul resulting in 30% reduction in assembly time.
• Added multi-depth file inclusion (Incasm).
• Batch mode for generating multiple files.
• GenerateTo directive extended for disk images (d64, d71, d81).
• BASIC import from D64, D71 and D81 images.
• The ‘@’ can be used to specify the start address/program counter.
• Case conversion for quoted BASIC strings.
• Bookmarks.
• Greater control over the data generation when including screen data in assembly source.
• The BASIC keyword PI has been changed to {PI}.
• Genesis assembler file format added to file conversion tool.
• The character editor’s scratchpad has been merged with the main edit form.
• The grid on the screen editor is now ‘behind’ the characters.
• Keystroke Macro recording/playback.

Bugs fixed:

• Some cheap label issues.
• Some projects not being built as the build order was incorrect due to ‘* =’ used when specifying the start address.
• Spaces around values in a WORD sequence were invalid.
• Assembly code reformatting issues.
• Reformatting assembly code which contained breakpoints.
• Reformatting assembly code which contains spaces.
• Breakpoints not being retained.
• Adding existing files to a project occasionally failed.
• Some assembler expressions not evaluated properly.
• Some assembler invalid variable names not detected.
• The BIT instruction in the debugger was not setting the overflow flag.
• Some memory overwrites not detected.
• Palette issues with C128 target machine.
• Some invalid byte sequences not reported.
• Emulator could start even after an invalid prg generation.
• Problems with global variables.
• Improved validation on options pages.
