Sending text from a STR variable

Ok I know this is a newb question but well I am one. How do i send the str variables in the belwo script to another program?
The variables are saved in excel spreadsheet and pull fine with the wscript.echo command but. I have tried the below commands to send it to a program called vista TN3270 emulator the program opens fine form the script but the data is not sent to screen.

I have used:
wscript
sendkeys
prtsc

none seem to work the way I need.

Below is script it is basic but once I figure this out I can build (or try to learn how to) the rest of what I need pulled from excel into the program.

Dim yourid, yourPSWD, strYourID

Set objExcel = CreateObject("Excel.Application")
Set objWorkbook = objExcel.Workbooks.Open _
("C:\ExcelSheet\ocean1.xls")

intRow = 2

Do Until objExcel.Cells(intRow,9).Value = nil
Wscript.Echo "YourID: " & objExcel.Cells(intRow, 9).Value
strYourID = "YourID" & objExcel.Cells(intRow, 9).Value
Wscript.Echo "YourPSWD: " & objExcel.Cells(intRow, 10).Value
'Wscript.Echo "Last Name: " & objExcel.Cells(intRow, 3).Value
'Wscript.Echo "Country Code: " & objExcel.Cells(intRow, 4).Value
'Wscript.Echo "Model ID: " & objExcel.Cells(intRow, 5).Value
'Wscript.Echo "Printer: " & objExcel.Cells(intRow, 6).Value
'Wscript.Echo "Station: " & objExcel.Cells(intRow, 7).Value
intRow = intRow + 1

Loop

objExcel.Quit

'Opens Ocean transmits Data

Dim objShell 'Holds WshShell object
Dim objExecObject 'Holds what comes back from executing the command
Dim strText 'Holds the text stream from the exec command.
Dim command 'The command to run

command = "cmd /c C:\VistaTN3270\vistaTN3270.exe Ocean.ses"
'WScript.echo "starting program " & Now 'Used to mark when program begins
Set objShell = CreateObject("WScript.Shell")
Set objExecObject = objShell.Exec(command)

PRTSC yourid

thank you for any help you can give. Also can anyone tell me why the belwo line does not stop once the cell in excel is blank? I use the below line:
Do Until objExcel.Cells(intRow,9).Value = nil

I have replace nil with blank and also tried 0 and put a 0 in the last sell it doesn't seem to care.

Oh I am also using PrimalScript to edit the scripts if that makes any difference.
