    Default Edit .asm files

    I need to edit .asm files to be compiled for Motorola 68000 Processors.

    Used to do it in Wordpad in Win NT4. They dropped support for saving this format in Win 2000.
    I still do it using a very old Laptop running Win 95 which is physically on it's last legs. Mechanical problems not electronic.

    Anyone know of a suitable program to open .asm Files ( Basically Text Files ) edit them and save in the same Format.
    They are simple files that are Assembled and then converted to .bin files for placing in an eprom.
    The Assembler and burning software are still DOS based, yet all work on the current Windoz.

    Everything I do with text files that are not a document I do with Notepad++
    So far I have not met a file it could not handle, and just checked ASM is supported as well.

    Any decent programmers text editor will work. Just be careful that it doesn't save the file as "Unicode".

    Notepad++ Does the job. Thank you.

    Microsoft removed the "Save all files" option from Notepad and Wordpad from Win 2000 and XP and on.

    normal notepad will work fine too.
    Either right click and "open with" or just change the extension to .txt and then later back to .asm

    Editing with Notepad was fine. Just could not save as .asm. Renaming did not work.

    Try unticking hide extensions for known file types in Folder Options - View, that should sort out your renaming issue.

    Or, when saving the file use "" as in "name.asm" it will save it as an asm file then, instead of a txt file.

    To save a .asm file in notepad simply select File/save as, select Save as type = All Files (*.*). Then name your file; anythingyoulike.asm.
    There is also 4 choices of Encoding; Default being ANSI.

    The problem is that the ALL FILES option is no longer there.
    That option is what I always used in NT4 amd WIN95.

    I had been using WORDPAD in NT4 for years. I can still dig out that computer and do it.
    Just cannot do it in WIN2000 or WIN7

    Don't know what's wrong with your version of Windoze, Reschs, my W7 lappy, and various desktops (XP forward) all allow me to save as in Notepad.

    Correct the option is not available with Windows Wordpad, it is however as I & others have stated available in all current Win OS versions of Notepad. 2 different programs?

    The fact is you have now the free open source program Notepad++ that obviously solves the problem for you. It is a slightly(lol) more advanced version of Win Notepad.

    I didn't actually know there was a program called , I thought post 2 was just giving Notepad the Thumbs Up.
    Don't worry Google set me straight on that.

    Always used Ultraedit myself which is a text editor on steroids.
    It has customisable syntax highlighting for just about any type of source file (asm, C, Java, HTML, VB etc) and a lot of other very useful features like hex viewing/editing object files etc etc. Way more features than I'll ever use and a good one is the ability to open a file that's already open in another application. Wouldn't be without it.

    For UltraEdit you (currently) have $79.95 USD to pay for, whereas NotePad++ is free of charge.
