re = /(^\d)(\d+)/;
str = "99999999";
newstr = str.replace(re, "$1-$2"

Your logic should work. It's just that your syntax is wrong.
In JavaScript, you can do a numeric to string casting by adding the number to a text string.
So
numStr = new String(num);
to be replaced by
numStr=''+num;
Then
newStr =
numStr.substring(0,numStr.length-1)+'-'+numStr.substring(numStr.length-1)
to be replaced by
newStr =
numStr.substring(0,numStr.length-1)+'-'+numStr.substring(numStr.length-1,numStr.length)

JPBURBE,
Which one doesn't work?
The one that I corrected your syntax or the one posted by iza?
I tested the former and it works.

Don't forget to put ; at the end of newStr =
numStr.substring(0,numStr.length-1)+'-'+numStr.substring(numStr.length-1,numStr.length);
numStr.substring(0,numStr.length-1)+'-'+numStr.substring(numStr.length-1,numStr.length);

the code i gave you works for sure (tested !!)
"What does this [re = /(^\d)(\d+)/;] do?"
--> ah ah that's why i gave you the url BEFORE the code - anyway .... this is a reg exp and it states that the expression it's looking for is of the form : xy where x is A SINGLE number and y is 1 or more numbers
and then the "str.replace(re, "$1-$2"" line says to write the expression this way : x-y
so if str was "999999999" you'll get x=9 and y=99999999 and it'll display 9-99999999 ------

there was noting about a form in any thread here - or did i miss that ???
and where the info comes from is not a problem, as you're only using a string - and in javascript pretty much anything can be a string - so all code given here should be working regardless you're writing a form, reading datas from vb or from a text file or anything else
now i've got troubles understanding this : "the dash is in the vb program but on the PDF form it doesn't show up"
- the string you're reformatting is "xxxx" or "x-xxx" ???
- you've got a vb program, you'll send datas to a web page that is sending them to a pdf ???
- where do you want the string to be formatted : in the web page or in the pdf ?
