 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |
Forum Index : Microcontroller and PC projects : V6.00.00RC5 will be the release unless you tell me ortherwise

Please can I encourage everyone to try V6.00.00RC15 and report any issues. This version will become the 6.00.00 final release unless any bugs are reported. Historically I make a release and only then bugs are found. I'd like to avoid this -this time! Please don't bother asking for any changes.......

Is it correct that counter variables used within sub routines are not local by default? ' local variable test Dim i = 99 Print "i=";i Sub test() Local i = 0 For i = 1 To 10 Print i Next i End Sub test() Print "i=";i results correctly in: i= 99 1 2 3 4 5 6 7 8 9 10 i= 99 If local i=0 within the sub is commented out, then the global i is used within the for next. I don't know why my expectation is that the a counter variable within a sub is always local to the sub - but may be this has its origin from other programming languages ;-) ' local variable test Dim i = 99 Print "i=";i Sub test() 'Local i = 0 For i = 1 To 10 Print i Next i End Sub test() Print "i=";i > run i= 99 1 2 3 4 5 6 7 8 9 10 i= 11 so the sub has modified my "global" i. -andreas |

Hello Andreas, Yes, as long as you dont declare them as local within a Sub or Function, they are global Cheers Martin 'no comment |

may be dangerous. if you have a complex program (longer than 1 page;) and some subroutines then you have to take care that all subroutine-variables are declared 'local' otherwise you risk funny value changes in the main program. -andreas |

Any variable not defined as local is global, including a loop counter. Same in every version of MMbasic that has ever been released |

I understand. Sometimes I use python ;-) (may be interesting in this regard: https://www.geeksforgeeks.org/global-local-variables-python/ ) -andreas |

Attempting to enter a date or time into system variables using the ENTER command results in an error both in the command line and from the program. > ? Date$ 01-01-2000 > INPUT Date$ ? 09-11-2024 Error : Variable name > ? Time$ 00:20:02 > INPUT Time$ ? 21:54 Error : Variable name Forgive me if it should be like this, I am a complete ZERO in MMBasic programming :) |

You can't use a function name for a variable name. try: > time$ = "07:10" > print time$ 07:10:07 > input tmp$ : time$ = tmp$ ? 07:15 > print time$ 07:15:06 > VK7JH MMedit MMBasic Help |

I used flash-nuke-uf2 and reflashed and now just the normal boot message geoff, peter. copied option list first.

So these are functions!?! And in some places they behave like variables!? time$ = "07:10" Edited 2024-11-10 06:29 by javavi |

They are listed under Functions in the manual. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Time$ and Date$ both appear in list commands and list functions. Jan. |

I think most, if not all, functions behave like variables. Their purpose is to return a value or string. eg X = Sin(a) Time$ is also a function as it returns a string. > now$ = time$ > ? now$ 06:47:35 > So far no issues found. Edited 2024-11-10 07:14 by phil99 |

You have option autorun set and the tokens have changed so the stored program is corrupt |

Simply do a new FLASH SAVE. all will be fine after that. Volhout PicomiteVGA PETSCII ROBOTS |

I have done a little bit of testing with CFunctions. They seem to be OK. An updated PicoCFunctions.h is attached. The same file for both PICO and PIO2, there is one #define to uncomment to use for the RP2350 i.e. /*** Uncomment this define if using PICO2 Chip ***/ #define PICORP2350 PicoCFunctions.zip This is the commandline used for the PICO2. "C:\Program Files (x86)\GNU Arm Embedded Toolchain\10 2021.10\bin\arm-none-eabi-gcc.exe" -c -mcpu=cortex-m33 --specs=nano.specs -mfloat-abi=softfp -mthumb -Wall -Wno-main -ffunction-sections -O0 -fPIC -I. %1.c -o %1.o IF ERRORLEVEL 1 Goto Done "C:\Program Files (x86)\GNU Arm Embedded Toolchain\10 2021.10\bin\arm-none-eabi-gcc.exe" -nostartfiles -T arm-gcc-link.ld -o %1.elf %1.o IF ERRORLEVEL 1 Goto Done Latest F4 Latest H7 |
