Python to VBScript conversion - vbscript

Question

I need to help in converting a Python script to VBScript. I'm trying to load the .cal file as a binary value file and edit a particular value in the file but unfortunately, my environment only supports VBScript.
import argparse
parser = argparse.ArgumentParser(description='Sapix Cal File Sensitivity Adjustment')
parser.add_argument("-calfile", default="test.cal", help="Enter the Calfile name (ex: 09781DK5081.cal")
parser.add_argument("-vtest", default=125, help="New Vtest setting (85-205)")
parser.add_argument("-vref", default=250, help="New Vref setting (250-120)")
args = parser.parse_args()
calfile = args.calfile
vtest = args.vtest
vref = args.vref
print(calfile)
print(vtest)
print(vref)
with open(calfile, "rb") as binary_file:
# Read the whole file at once
data = bytearray(binary_file.read())
# Find Line with VTEST setting
ivteststart = data.find(bytearray('PARALLEL_VOLTAGE_TEST', 'utf-8'))
ivtestend = data.find(b'\n',ivteststart)
# Remove original VTEST line
del data[ivteststart:ivtestend+1]
# Insert New Line with new VTEST
new_vtest = bytearray("PARALLEL_VOLTAGE_TEST %s\n" % (vtest),'utf-8')
data[ivteststart:ivteststart] = new_vtest
# Find Line with VREF setting
ivrefstart = data.find(bytearray('PARALLEL_VOLTAGE_REF', 'utf-8'))
ivrefend = data.find(b'\n',ivrefstart)
# Remove original VREF line
del data[ivrefstart:ivrefend+1]
# Insert New Line with new VREF
new_vref = bytearray("PARALLEL_VOLTAGE_REF %s\n" % (vref),'utf-8')
data[ivrefstart:ivrefstart] = new_vref
# Write new sensitivity settings to cal file
with open(calfile, "wb") as binary_file:
binary_file.write(data)
I was able to make the changes if I load the file as text file but I have no clue how to load the same as Binary value and make the changes

Take a look at the following post: Read and write binary file in VBscript. You might be able to use ADODB.Stream to read and write binary data. Other approaches are explored also, including reading characters one by one into an array.
Here's the code from that post:
Function readBinary(strPath)
Dim oFSO: Set oFSO = CreateObject("Scripting.FileSystemObject")
Dim oFile: Set oFile = oFSO.GetFile(strPath)
If IsNull(oFile) Then MsgBox("File not found: " & strPath) : Exit Function
With oFile.OpenAsTextStream()
readBinary = .Read(oFile.Size)
.Close
End With
End Function
Function writeBinary(strBinary, strPath)
Dim oFSO: Set oFSO = CreateObject("Scripting.FileSystemObject")
' below lines pupose: checks that write access is possible!
Dim oTxtStream
On Error Resume Next
Set oTxtStream = oFSO.createTextFile(strPath)
If Err.number <> 0 Then MsgBox(Err.message) : Exit Function
On Error GoTo 0
Set oTxtStream = Nothing
' end check of write access
With oFSO.createTextFile(strPath)
.Write(strBinary)
.Close
End With
End Function
