I have limited skills when it comes to bat files, and am not experienced with using loops,
 which I think that is what is needed in this case.

 I am writing a bat file that will take an input string from the user and then act on the string.
 But I need to check that string aginst a list of invalid characters, including spaces which I don't
 exactly know how to add to the list of characters.

 set invalidlist="`~!@#$^&*()=+[]{}\|;:'",<>/?"
 set invalidchar=" "
 set string=

 set /p string= enter your string
 for loop here check for invalid chars (?)
 if invalid chars are found goto badchar
 if not bad chars are found, goto work
 echo you cannot use spaces of any of the following characters
 echo `~!@#$^&*()=+[]{}\|;:'",<>/?    <---<< also ow can you echo these and get them to show up as output?
 goto start
and so on......

   Does this make sense? I guess basically, the user enters a string and presses enter, the function would look at each character
  and compare it with each invalid character and if there is a match there it will error out and make them re-enter a string again.
  if there are no errors found it will continue on.
