if so, you should probably create a git repo outthere so people can
easily deploy, comment, contribute ...

Re: decvers.vim
hello Mark,
As you posted the whole script on the list, you probably expect some
feedbacks so mine is:
I script a lot of things and what I consider a good practice is the
complete oposite of what you're trying to achieve here: If your code is
useful, someone will probably want to use it out of vim so don't use
viml and pick another scripting langage (zsh, dash, rc, tcl, perl, js,
ruby, python, R, there are tons of those) then use it from vim using
! or system* functions.
Also: take a look at vim9script: it it much more confortable than the
old style vim langage.

Marc

decvers.vim
First, sorry for top posting. I was just replying to my email. Live and learn as they say. Now I know to not do that. I'll try to always go to the list and post there from now on. Again - very sorry.

I decided to post my decvers.vim script here in case anyone out there would like to use it. Why is it called decvers.vim? The "dec" part comes from the Digital Equipment Corporation or DEC name. The "vers" is for the word "version". Thus decvers.vim.
What it does is to make a copy of your source code automatically. It does this by adding a semicolon (;) to the end of the file name and then adding a five digit number to the end of the file name also. (So like "00000" or "00001" and so on.) Each time you edit the file, it adds one new number onto the end of the save (I have it set to do this three times). When you reach the maximum number of saves the earliest version is removed. Thus, you don't over run your system with backup copies. The interesting thing about this is that this shows you how you could do an automated version number in the program but I'm just interested in just having a backup I can return to if somehow I manage to muck up the current version. Anyway, here is the code. It is not perfect but it works. :-)

Re: Q&A: MSDOS SET command gave me some of my mapped commands
One last message. Plus zero did not work. Yes, it is acting as if it
were octal. Vim should not really do that as sometimes people do put
zeros in front of the number. (At least, this old fogey remembers when
people used to do that all of the time.) Here is what works:
str2nr( $value, $type )
So I used str2nr( $ext, 10 )
And that forced it to keep the number as 10. Just thinking aloud here
but it would be nice to have 0b for binary, 0c for octal, 0x for
hexadecimal, and 0d for decimal. But I guess no one wants to do that.

You can include the script verbose on the list, don't need to send it to
me. So the whole list audience has a chance to chime in.
My guess is the value is seen as octal, and therefore Vim is increments
it in octal mode (00010 -> 8 decimal).
Instead of incrementing a string value, I'd recommend to perform the
actual arithmetics using a decimal number and then use printf() to
convert it into a string value.
Thanks,
Christian
