This post repeats the processes and discussions of last post for saving as CSV Macintosh and CSV MS-DOS. ( We will assume we only have one worksheet showing at the start , so will not have the initial pop up warning ( https://imgur.com/QLscU1a )

Macintosh
We record a macro whilst doing Save, SaveAs , Close.
We find that we get the following warnings, answering always Yes

Save or SaveAs

Here is the macro obtained from the recorder.
Code:
Sub SaveSaveAsCloseMacintoshCSV() '  https://excelfox.com/forum/showthread.php/2559-Notes-tests-text-files-manipulation-of-text-files-in-Excel-and-with-Excel-VBA?p=13741&viewfull=1#post13741
' Save manually
 ActiveWorkbook.Save
 ' SaveAs manually
 ActiveWorkbook.SaveAs Filename:="F:\Excel0202015Jan2016\ExcelFox\vixer\csv Text file Chaos\CSV (Macintosh)A1B1A2.csv", FileFormat:=xlCSVMac, CreateBackup:=False
' Warnings same for both: https://imgur.com/jCJ5XjK

' Close manually
 ActiveWorkbook.Save: ActiveWorkbook.Close
' two warnings obtained : https://imgur.com/sShcoNq , https://imgur.com/Q20iknI
End Sub
This is what it the produced text file, like in a text editor
answering always Yes
cellA1;cellB1cellA2;

Note: if I copy and paste that into Word, then I get
cellA1;cellB1
callA2;

Analysing what is there I see the typical results expected for a Macintosh csv file
"cellA1" & ";" & "cellB1" & vbCr & "callA2" & ";" & vbCr & vbLf

If I say No on the Close, then I get only that warning: The file closes without the second warning. But the results are the same


If I run the recorded macro, ( on a newly made file ) , then there is no warning pop up on Save or SaveAs. I just get the single warning asking me if I want to save the changes on Close ( despite already with the preceding coding having Saved and SaveAsd and Saved before the Close

The resulting text file has commas , for the separator
CellA1,CellB1CellA2,
I get the same results if I answer Yes or No to the warning


CSV (MS-DOS)
We record a macro on Save, SaveAs , Close. We get the following warnings, answering always Yes

Save or SaveAs

This macro is obtained
Code:
Sub ManualSaveSaveAsCloseCSV_MS_DOS_()
 ' Manual Save
 ActiveWorkbook.Save
 ' Manual SaveAs
 ActiveWorkbook.SaveAs Filename:="F:\Excel0202015Jan2016\ExcelFox\vixer\csv Text file Chaos\CSV (MS-DOS)A1B1A2.csv", FileFormat:=xlCSVMSDOS, CreateBackup:=False
 ' warning same for both https://imgur.com/vkikEUS
 
 ' Close manually
 ActiveWorkbook.Save: ActiveWindow.Close
 ' two warnings obtained https://imgur.com/uvh64E6 , https://imgur.com/sCPSmFX
End Sub
If I say No on the Close, then I get only that warning: The file closes without the second warning. But the results are the same.

The resulting text file looks like this
cellA1;cellB1
callA2;

If I run the macro produced from the macro recording, then I only get the first warning on at the Close

It makes no difference if I answer Yes or No
The results are that I get a file with comma , as the delimiter
cellA1,cellB1
callA2,



Final Conclusions on Save SaveAs Close for the 3 CSV file types
The following conclusions are in general identical for the three CSV types
In my Excel, if I try to save or close manually a file as CSV type, then the separator becomes a ;
Any attempt to do the same with a macro always results in a , as the separator, ( even if the macro had been derived from a macro recording when doing it manually which resulted in the ; as separator ).
It makes no difference to the results by selecting a YES or No on any of the two possible prompts on a Close.
( The single prompt on a Save or SaveAs gives me the chance to go back to the save dialogue to choose an extension other than .csv)
