Sample Powershell script:

$InputFile = "C:\data\original.txt"
$OutputFile = "C:\data\newdata.txt"

Function ParseText ($OutputFile,$InputFile){
Begin{
$newdataline,$totline,$total = $NULL,$NULL,$NULL
Set-Content $OutputFile $null
}
Process{
      Get-Content -Path $InputFile | % {

If ($_ -match "AIS\*1"){
      If ($poline -ne $null -and $total -ne $null){
      $Totline = "Total: `$$Total"
      write-host "This is Total `$$total"
            "`n$newdataline `r`n$totline" | out-file $OutputFile -Encoding UTF8 -Append
            $newdataline,$totline,$total = $NULL,$NULL,$NULL
      }
}
   If($_ -match "(G50\*)(\d{0,10})") {
      $newdataline = "New Data: $($Matches[2])"
    }Elseif ($_ -match "G48"){
        $col=$_.split("*") ; $total += [double]$col[2] * [double]$col[4]
  }
 }
}
}

if (Test-Path $InputFile){
     ParseText $OutputFile $InputFile
}


Desired output:

New Data:  44444 (from the G50 line)
Total:  $ (the total of the data in the G48 lines.  (ie as per above - 10 x 10.05 + 25 * 15.00)

What modification needs to be made to the script so that the newdata.txt file is showing accurate data?

based on the input data, following code should give you the expected result..
$InputFile = "C:\data\original.txt"
$OutputFile = "C:\data\newdata.txt"

Function ParseText ($OutputFile,$InputFile){
Begin{
 $newdataline,$totline,$total = $NULL,$NULL,$NULL
 Set-Content $OutputFile $null
}
Process{
Get-Content -Path $InputFile | % {
  If ($_ -match "IEP\*1"){
    If ($newdataline -ne $null -and $total -ne $null){
      $Totline = "Total: `$$Total"
      write-host "This is Total `$$total"
      "`n$newdataline `r`n$totline" | out-file $OutputFile -Encoding UTF8 -Append
      $newdataline,$totline,$total = $NULL,$NULL,$NULL
      }
 }
   If($_ -match "(G50\*N\*\d{1,}\*)(\d{0,10})") {
    $newdataline = "New Data: $($Matches[2])"
    }Elseif ($_ -match "G48"){
    $col=$_.split("*") ; $total += [double]$col[1] * [double]$col[3]
  }
 }
}
}

if (Test-Path $InputFile){
     ParseText $OutputFile $InputFile
}
