# Old BASIC, C and other source code

{{< snippet "old" >}}

## Source Code

I plan to move all of this to {{< snippet "jp-github" >}} at some point...


### Batch Files

See my {{< xref "../windows/winshell.html" "Windows Shell Scripting" >}} page.

-----

### (UNIX) Shell Scripts

  - [checkmd5sum](/public/source/checkmd5sum.txt)
    A trivial script to compare MD5 hashs for downloads ISOs and
    software.
  - [web](/public/source/web.txt)
    A simple wrapper for use with [GenSite.pl](perl.html#gensite).

-----

### C, (& BASIC)

See *[Dave Navarro's](http://www.basicguru.com/navarro/)* Win32 console
*[CMD Tools](http://www.cmdtools.com/)* written in BASIC.

  - [Pause.c](/public/source/pause.c.txt)
    A tiny C program that does the same thing as the DOS pause command.
  - [UUConvert.c](/public/source/uuconvert.c.txt)
    An old program that reassembles and uu-decodes binary Usenet threads
    saved by old mail readers such as Tin. I did not write this and I
    don't know who did.

### Assembly `SCR` programs

  - [WrmBoot.com](/public/tools/wrmboot.com) and
    [CldBoot.com](/public/tools/cldboot.com) (16bytes)
    A Warm Boot (CTRL-ALT-DEL) and Cold Boot (same as reset switch) on a
    PC. Here is the C, BASIC, and debug .scr [source
    code](/public/source/rebt-src.html).

This [zip file](/public/source/Scr.zip) is a collection of old "scr"
programs, many collected from old computer magazines. Here is a listing:

### Other

Here's a very [simple awk script](/public/source/ascii2html.txt) to
prepare text for inclusion into a HTML file by changing URL's in a
plain-text file into into HTML links to that URL. I'm not really sure
who wrote it, but I didn't.

See this [zip file](/public/source/date_related_source_code.zip) for
some date and time related code and routines. I didn't write any of this
either.
