CBM prg Studio Version 2.5.0 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:

• Some of the IDE’s colours can be changed (background, tab strip, selected and non-selected windows).
• Menu to control open windows.
• Warnings if invalid BASIC jump (goto, gosub etc.) destinations are detected.
• ZPOpt directive added.

Bugs fixed:

• Added ‘missing’ colours to VIC 20′s screen designer.
• Default project location not being saved if the target machine was not changed.
• Assembler not assembling mixed case text directive strings properly.
• Dark and light gray colours were switched.
• Opening a project after a project had already been opened would use ‘my documents’ rather than the project directory.
• Incbin failed when used screen designer files.
• No colours were visible when starting the screen designer without loading a previous file.
• CTRL+Z not scrolling to changed text.
• * not recognised for current address.
• Local labels not recognised in certain circumstances.
• Generation/import of prgs > 65k for C128 programs would fail.
• Missing BASIC 7 ‘RLUM’ keyword.
