Question

I need to know how to read data from tabbed delimited text file in order to export merged documents to correct location.

— will always be 4th tab 2nd row (group number) directory will be named by group number

— have directories already created by privious .vbs script

data will have to be placed:

app.open(File(dirPath + "Card~" + (group number) + ".indd"));   

and also:

fileName = (group number) + " " + myPageName + " " + date + ".pdf";        
        myFilePath = dirPath + docType + "/" + fileName;
        myFile = new File(myFilePath);
        myDocument.exportFile(ExportFormat.pdfType, myFile, false);

within previous .vbs script to work with this data file was written as so:

How can I achieve something similar in .jsx?

Figured it out this will read 1,3 and create a variable for group number 1,3

 var aFile = File("P:/RxCut/In Design Implementation/build/automate/automate.txt");
    var fileData = readTabDelimitedFile ( aFile ) ;
    //$.writeln(fileData[1][3]); //should contain first tab on second line
    tstdata = fileData[1][3];
    var group = tsdata
    function readTabDelimitedFile ( fPath ) {

    var returnArray = new Array ( ) ;

    //-- Verify that the file exists
    var fileObject = File ( fPath ) ;
    if ( ! fileObject.exists ) {
    return returnArray ; // an empty array because the file doesn't exist.
    }
    //-- Create a regular expression for a tab.
    var tabExpression = new RegExp ( '\\t' ) ;

    //-- Read the file.
    try {
    //-- The file has to be open.
    fileObject.open ('r') ; //-- Open for reading.

    while ( ! fileObject.eof ) {
    var currentLine = fileObject.readln () ;

    if ( tabExpression.test( currentLine ) ) {

    returnArray.push(currentLine.split ('\t')) ;
    }
    }
    fileObject.close() ;
    }

    catch (errMain) {
    try {

    fileObject.close() ;
    }
    //-- if the close generates an error skip it.
    catch (errInner ) { /* nothing here */ }
    }

    return returnArray ;

    var group = returnArray 
    }
