Gary and Claus, this is the problem that I presented earlier. Can anyone
identify why the first function works perfectly, but the second function
fails? The second function reads data from "C:\data.txt", which only
contains "a123 Go now 123".

The output is supposed to be "Go now 123", but only the first function works.
Both functions are essentially the same, except that the second one reads
data from a file.

Is it possible that loading a file string into a variant type causes
problems?

'-------------------------------------
Sub ThisWorks()

Dim sline As String

sline = "a123 Go now 123"

sline = Application.Substitute(sline, " ", "*", 1)
varTmp = Split(sline, "*")

MsgBox Trim(varTmp(1)) ' It works! It returns "Go now 123"

No.., it returns " Go now 123" BECAUSE sline has 4 spaces between "a123"
and "Go now 122" and your formula only replaces 1 of those spaces, leaving the
other 3 part of the 2nd array element.

End Sub


'-------------------------------------
Sub ThisFails()
Dim n As Integer, i As Integer, RowNmbr As Integer
Dim varOut() As Variant
Dim sText As String
Dim sPath As String
Dim sline As String

sPath = "C:\data.txt"

'Open file for read
Open sPath For Input As #1

Do Until EOF(1)
RowNmbr = RowNmbr + 1
Line Input #1, sText
If (Len(sText) = 0) Then
GoTo NFR_ENDLOOP
End If
If StrChk(sText) = True Then
ReDim Preserve varOut(i)
varOut(i) = sText 'RowNmbr
i = i + 1
End If
NFR_ENDLOOP:
Loop
Close #1

sline = varOut(0) ' Read the first line: "a123 Go now 123"

sline = Application.Substitute(sline, " ", "*", 1)
varTmp = Split(sline, "*")

MsgBox Trim(varTmp(1)) ' Fails to output "Go now 123"

End Sub

This works as expected...

Sub ParseTextFile2()
Dim vTmp
Const sLine$ = "a123 Go now 123"
vTmp = Split(Application.Substitute(sLine, " ", "*", 1), "*")
Debug.Print Trim(vTmp(1))
End Sub

...and so does this...

Sub ParseTextFile2()
Dim vTmp, sLine$
Const sFile$ = "C:\Data.txt"
sLine = ReadTextFile(sFile)
vTmp = Split(Application.Substitute(sLine, " ", "*", 1), "*")
Debug.Print Trim(vTmp(1))
End Sub
