I really need help with "KEYASCII =13"

[mxnmx]

This is the code that creates a file that makes the output look like this in HexViewer:
000001Michael Jackson.000001.123456.445112
The above line has a certain records...Serial number,name,id number...all assumptions...and in the same file the second record is like this
000002Bill Clinton.001201.5343432.456789 and in the third record will have the first field as 000003.
What I want is that the first record will have
000001Michael Jacson.000001.123456.445112 and then I don't want this number to increment till the 4 the record so the 4th record should look like this:
000002Bill Clinton.....
and then the 8th Record will look like
000003William Gates.....
I want this number to increment after pressing enter 4 times, but am unable to do it, could anyone help....and in the last line I'm removing 0Ah by CHR$(13), I also wanna remove 0Dh, as the final output file will be viewed in HexViewer.

If KeyAscii = 13 Then
lMyNumber = CLng(sMyNumber)
lMyNumber = lMyNumber + 1
sMyNumber = Format(CStr(lMyNumber), "000000")
Print #1, sMyNumber & Trim(txtInput(0).Text); Chr$(13)
Print #1, Trim(txtInput(1).Text); Chr$(13);
Print #1, Trim(txtInput(2) + txtInput(3)); Chr$(13);
Print #1, Trim(txtInput(4).Text); Chr$(13);
txtInput(0).SetFocus
Print #1, Trim(txtInput(2).Text) + Trim(txtInput(3))+ Trim(txtInput(4)) Chr$(13);

End If

Try something like

Dim Counter As Long
If KeyAscii = 13 Then
    Counter = Counter + 1
       If Counter > 4 Then
          'do something when the counter hits 4
       End If
    lMyNumber = CLng(sMyNumber)
    lMyNumber = lMyNumber + 1
    sMyNumber = Format(CStr(lMyNumber), "000000")
    Print #1, sMyNumber & Trim(txtInput(0).text); Chr$(13)
    Print #1, Trim(txtInput(1).text); Chr$(13);
    Print #1, Trim(txtInput(2) + txtInput(3)); Chr$(13);
    Print #1, Trim(txtInput(4).text); Chr$(13);
    txtInput(0).SetFocus
    Print #1, Trim(txtInput(2).text) + Trim(txtInput(3)) + Trim(txtInput(4)); Chr$(13);
End If
