Incrementally name file with saveAs

Question

Hello all,
I am trying to create a script that names the active file as w1.pdf, and then subsequently would name the file w2, etc.
If one were working on w9.pdf and ran the script, you guessed it..........w10.pdf
Can I use the increment operand with saveAs? All of my efforts just keep adding stuff to the file name, not incrementtally changing the file name.
Thanks in advance for any help,

Hello Kent,  Yes of course this can be done.  But of course it has to be done from a folder level script, since the saveAs function cannot be used from a document script.
The basic technique is to acquire the file name, determine whether or not it matches the expected format, and parse out the current number.  Then increment the number and generate a new file name.
For example, this code uses a regular expression to perform the task:
// Match "w" followed by one or two digits
var rgFlNm = /^w(\d{1,2})/;
if(rgFlNm.test(this.documentFileName))
   var newFileName = "w" + (Number(RegExp.$1) + 1).toString();
   this.saveAs(newFileName);
else
   app.alert("File Name does not match expected format");
the code here displays an alert if the file name format does not match "w" followed by one or two digits.  But you could have it default the file name or ask the user what they want to do.
