Import text into a form from a tab delimited file using an action

Question

Good evening.
I am using Adobe Acrobat XI Pro
I have been working all weekend so far on this, and have tried many options.
What I am wanting is to import a line of data from an excel file into a form, save the file with a name drived from the form fields, close the new file, then go back to the original file, import a line of data, and so on and so on.
I had all of this working in livecyle with a tool, but now that we are going to Windows 8 and Microsoft Office 2013, the driver that I need to load the excel file into the form is not available--so now I have to redo the forms in Adobe and import using a tab delimited file.
I would like to do this with an action.
Thus far, I have the following.
**Credit goes to George Johnson who helped me with the script to save the file using field names a few months ago**
To start, I have a folder level script
mySaveAs = app.trustPropagatorFunction(function(doc,path)
app.beginPriv();
var myDoc = event.target;
myDoc.saveAs(path);
app.endPriv();
myTrustedSpecialTaskFunc = app.trustedFunction(function(doc,path)
//privileged and/or non-privileged code above
app.beginPriv();
mySaveAs(doc, path);
app.endPriv
//Privileged and/or non-privileged code below
For the Action, I start with the Form file loaded
Then I execute a javascript to import the text into the file.
this.importTextData("/c/data/clerical.txt");
The next step is to save the file using field names as part of the file name
--credit goes to George Johnson who assisted me with this on a similar project a few months ago.
//Get the Field Value
var fn=getField("Last").valueAsString + "-" + getField("First").valueAsString;
//Specify the folder
var fldr = "/c/data/";
//Determine the full path
var fp=fldr + fn + ".pdf";
//save the file
myTrustedSpecialTaskFunc(this, fp);
That is as far as I have gotten. 
What I want to do now is load the original form file, import the next line into the form, save the file, repeat.
If anyone could assist me, I would greatly appreciate it.
**note  I had to type this from my I-pad because I kept getting kicked off the internet from my computer.  I hope my code is typed correctly.

Thank you so much for your response.
Yes--there are multiple lines in the data file--it will vary from month to month.  It looks like from what you are saying is that I need to do the global variable since it will constantly change, and then increment it as it goes through the text file.  When it reaches the end, then it will stop.
I looked at the following links--but this is from Adobe 9 API--I don't know if things have changed with XI--especially since 9 used batch processing and XI has actions.

I am not exactly sure how to include this in my code.
If you could point me in the right direction, I would appreciate it.
