Required Dos Programing how to write code for dos - like *.bat

All the information you'll need is in the help dialogs, just type "help" at the command prompt and it'll list all the commands available. Then just type a command followed by /? and it'll show all the help for that command:
C:\current_directory>echo /?

For what you described above, you may want to look at "set", "if", "echo", "goto" for starters.

A few tips:

type "set" to display a list of all system variables (DATE is a sytem variable!)use the "@" sign to turn echo off for the current line onlyyou can use "%n" to pass variables into the batch file (ex: typing "mybat.bat blah crap", then in your bat file you can sayif "%1"=="blah" start blah.exeif "%2"=="crap" goto craphere's a little code to get you started:CODE@ECHO offCLSECHO:This is my batch fileREM enter comments hereIF /i "%1"=="skip" ( ECHO:You must not care what day it is GOTO endofprogram)SET dayofweek=%date:~0,3%IF "%dayofweek%"=="Fri" (  ECHO:It's Friday!!) ELSE (  ECHO:Nope, not friday yet):endofprogramECHO:ECHO:PAUSE

I'm sure there are some good tutorials out there, but this will at least get you started
