Is there a clipper function for browsing a text file? All I want to do is display it on the screen and move up and down the display. I do not want to edit the text, only display it.

Yup. MEMOEDIT().
It works for text files even.
It takes upto 13 parameters like:
- Source (memo filed name or text/char stirng,
- Screen co-ords (4 paramaters),
- Updatable flag
- User defined functions ..
and so on
For more, refer to your on-line NG help or the manual.

I think we are getting a little closer with Memoedit(). I have used that to display contents of memo fields in databases, but have not use it to display a text file. I will read up on it but I was hoping that someone had a short snippet of code that would open and display a dos text file, similar to the way notepad would display it.

Hi,
Here's some code
Use the Mody_Memo function like this:
the underlying stuff is as follows:
MemoFunc is called as a key handler by MemoEdit (you can see it passed the reference above)
D_Msg is a very very old function that I wrote to display things on the bottom line of the display:
I use a C routing for the BGC (backgroundcolour) function
that D_Msg calls to shade the boxes - but here is a Clipper variant:
Lastly, here is a 'drop_box' function to make things pretty:
Put it all together and you have an edit memo function:

If you want to force a readonly state change the sixth parameter in the Memoedit call to be false:
(change your D_msg line as well:
And I forgot the colors[] array and F4 definition so you could run it! put this snippet at the top of the code:

This may be just what your looking for.
cFile is the text file you want to browse and must include the full path (if not in current directory) and filename with extention.
For Example:
TxtBrowse("c:\myfolder\myfile.txt"
It requires linking the Nanfor.lib which may be obtained at:
PROCEDURE TxtBrowse(cFile)
LOCAL cColor := SETCOLOR()
LOCAL cScreen:= SAVESCREEN(4,9,11,71)
@ 4,9 TO 11,71
FT_DFSETUP(cFile, 5, 10, 10, 70, 1,14, 1,;
CHR(27), .T., 5, 132, 4096)
FT_DISPFILE()
FT_DFCLOSE()
SETCOLOR(cColor)
RESTSCREEN(4,9,11,71,cScreen)
RETURN
This is a partial quote from the Norton Guide for the Nanfor.lib
Syntax:
FT_DFSETUP( <cInFile>, <nTop>, <nLeft>, <nBottom>, <nRight>,;
<nStart>, <nCNormal>, <nCHighlight>, <cExitKeys>, ;
<lBrowse>, <nColSkip>, <nRMargin>, <nBuffSize> ) -> nResult
Arguments:
<cInFile> - text file to display (full path and filename)
<nTop> - upper row of window
<nLeft> - left col of window
<nBottom> - lower row of window
<nRight> - right col of window
<nStart> - line to place highlight at startup
<nCNormal> - normal text color (numeric attribute)
<nCHighlight> - text highlight color (numeric attribute)
<cExitKeys> - terminating key list (each byte of string is a
key code)
<lBrowse> - act-like-a-browse-routine flag
<nColSkip> - col increment for left/right arrows
<nRMargin> - right margin - anything to right is truncated
<nBuffSize> - size of the paging buffer
Returns:
0 if successful, FError() code if not
