Hi Jiri and Tom, I was thinking of inserting line splits at fixed intervals to work around the limitation, but that still wouldn't be editor-friendly. The intent is to create self-extracting archives, most of which wouldn't fit into an editor anyway, but the expectation is that .bas files contain only text and I should respect that (this in contrast with a .PRG on C64 which typically contains a mix of Basic and binary). Base64 encoding or something like that would indeed do the trick. It'll be a bit more work than I was hoping for, but still doable. Thanks for the feedback! Epsilon CMM2 projects |

I appreciate the "container" impulse to get everything into a single portable .BAS file, but you wouldn't attempt that with media assets, each of which has its own dedicated file format. Most OSes, even vintage 8-bit ones, support some form of raw binary file e.g. the Apple II DOS has BLOAD and BSAVE commands for binary data, and a BRUN command that loads and launches an executable ML program. Maybe the facility to save and load a stream of bytes is something Peter can consider as an enhancement request for the "MMOS". Enjoy Every Sandwich / Joe P. |

@Jiri, well, that was easy  Thanks for pointing that new feature out!@Epsilon, does that new SAVE DATA / LOAD DATA combination address your use case? Seems a lot more elegant than trying to encode / decode binary data within a BASIC comment block. This topic reminds me of both Microsoft and Apple trying to convince us for twenty years that we absolutely needed compound office documents, but never actually getting it to work right in all that time. OLE has always been a hot mess. IMHO, the only legitimate use case for a compound file format is streaming media, wherein the video and multiple audio and subtitle streams must be synchronized and distributed as a single file. And, similarly, we are still fighting the "media container wars", with no clear winner. I am betting on MKV, though - open standards always win over proprietary ones in the end. Enjoy Every Sandwich / Joe P. |

V5.07.00b24 now available http://geoffg.net/Downloads/Maximite/CMM2_Beta.zip Fixes a bug where static variables with the same name in different subroutines conflict when used in an interrupt routine. Thanks Geoff |

I'm creating a self-extracting version of the .MAR/.MZ1 archive, roughly equivalent to self-extracting zip files, i.e. when you execute them, they unpack themselves. The idea is to make it easy to publish complex CMM2 applications, e.g. games, that consist of multiple files. SAVE/LOAD DATA doesn't help with that, but the earlier proposal to use base64 encoding solves it nicely. I base64 encode the archive and store it in a COMMENT START/END block. I have verified that this works even with comment blocks larger than CMM2 memory (I used a 6.5MB block to test). The base64 encoding will increase the file size by 33%, and will increase the unpack-time, but I think that's acceptable. Epsilon CMM2 projects |

What am I doing wrong now? mode 1,8 cls pause 1000 ? "Test" do DrawHLine 50,750,500 loop sub DrawHLine x1,x2,y do : loop until getscanline > MM.VRES line x1,y,x2,y,20,0 line x1,y,x2,y,20 end sub On my system (400MHz, MMBasic Version 5.07.00b23), the above hangs on the "do : loop until getscanline > ..." Comment this line out and it runs - poorly. Different values of the comparison behave the same. If I comment out the very first line (mode), the program will run from the editor, but not from the prompt. The pause in line 3 seems to have no effect. The purpose of this was to try draw things cleanly without flicker by waiting for the scanline to get 'out of the way'. Works great when it works. Yes, I know there are other, perhaps better ways to draw cleanly, but ... Visit Vegipete's *Mite Library for cool programs. |

Is it the same with while? DO WHILE GETSCANLINE<MM.VRES LOOP Jiri Napoleon Commander and SimplEd for CMM2 (GitHub), CMM2.fun |

"DO WHILE GETSCANLINE < MM.VRES : LOOP" doesn't work either. The weird part is that, with MODE 1,8 commented out, the program runs from the editor but not from the prompt. The DO WHILE version behaves the same. "DO : LOOP UNTIL GETSCANLINE < 1" does work, although there is tearing on the top line. This might serve my purposes.

And if you try to use interrupt routine from MODE? DIM INTEGER blank=0 mode 1,8, intr cls pause 1000 ? "Test" do DrawHLine 50,750,500 loop sub DrawHLine x1,x2,y do : loop until blank line x1,y,x2,y,20,0 line x1,y,x2,y,20 blank = 0 end sub SUB intr blank=1 END SUB Jiri Napoleon Commander and SimplEd for CMM2 (GitHub), CMM2.fun |

Nothing - it is a bug Workround is to change mode to something other than 1 and then back to 1 mode 2 mode 1,8 cls pause 1000 ? "Test" do DrawHLine 50,750,500 loop sub DrawHLine x1,x2,y do : loop until getscanline > MM.VRES line x1,y,x2,y,20,0 line x1,y,x2,y,20 end sub Trivial fix in next beta Edited 2021-04-07 17:27 by matherp |

V5.07.00b12 now available http://geoffg.net/Downloads/Maximite/CMM2_Beta.zip Fixes bug in getscanline when mode is set at the beginning of a program and the default mode is the same. Inconsistency in manual for PAGE COPY. Transparent mode is initiated with T not 1 as specified in the manual. Both available from 5.07.00b25 |

In chrome, win10, I no longer have the file downloaded when I click on the link above. For some months, I've had to right click on it, "open in new tab", and it downloads and the new tab disappears. As of a few days ago, that no longer works either, I have to right click, "Copy Link Address", open a new tab, paste address and <Enter>. Then it downloads and I have to close the tab. Anyone have any idea what is going on and how I fix it back to the way it was when I clicked on the link and it immediately downloaded?

I have the same issue. It also downloads if you go "Incognito", it's probably a feature for our safety and security. Best wishes, Tom MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

I have the same issue as well. I think chrome thinks it 'unsafe' for some reason. I right click on the link then click on 'save link as', chrome doesn't want to download it until I click on the '^' down the bottom and then click on 'keep'. Bing seems to be OK. Bill Keep safe. Live long and prosper. |

The current download is at B25 but I can find no mention of that version. What has changed in B25? |

Thank you for the fix - it works awesome! ============================= Could you comment on IMAGE SAVE in conjunction with 8 bit (palette based) mode and modified palettes? The screensave command I put into "Escape to the Green Hills" and the latest postings on the "MAPSTER tile engine" thread indicate that I and maybe others are struggling with the results we are getting.
