SWEET! You've got me excited now. VBScript is much more powerful than it appear at first glance.
so the key to accessing the command line parameters is:
WScript.Arguments
which would be an array I guess, based on spaces between words? So if you used the command line argument:
what month is it?
WScript.Arguments would be equal to ["what","month","is","it?"] does that sound correct?
and if you surrounded your argument with quotes, would it come through as a single element in the array?
I also notice that you use a for next loop, which is fine, but I like to use For Each loops when going through a list of items mostly because it is easier to read.
e.g.:
For Each arg In WScript.Arguments
...do something with arg
Next
