E’ stata rilasciata una nuova versione del programma CBM prg Studio. Ci sono un sacco di nuove funzionalità e fix in questa versione e sono sempre gradite le segnalazioni di bug o suggerimenti/commenti.

CBM prg Studio e’ un kit di sviluppo che gira in ambiente Windows e vi permette di programmare in Commodore Basic e Linguaggio Macchina(LM), il programma potrà poi essere compilato in un file eseguibile “.PRG” per Commodore 64 / VIC-20 o PET.

La suite è anche completa di un ottimo sprite editor che permette di definire fino a 128 pattern, nonché di un funzionale char editor, che permette di avere una gestione completa e sotto controllo della procedura per la ridefinizione del charset interno al C64 e al Vic20.

Infine il CBM prg Studio, offre una completo e facile controllo della complessa gestione della tastiera del C64 e Vic20 ed in particolare dei caratteri PETSCII che contraddistinguevano le macchine sotto il marchio Commodore e che rappresentavano una chiave fondamentale per la programmazione in ambiente Basic, alla stregua di un vero e proprio macro linguaggio.

CBM prg Studio sostituisce le ormai obsolete Tools: C64PrgGen e VIC20PrgGen.

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.
