It depends on what is being used to display the string. The VB6 command window uses a variant of the textbox, and will interpret CRLF as a carriage-return line-feed combination, and move the caret to the next line.
If you need to see these values, convert the string to hexadecimal before displaying it.

Ad$ = chr(10)&chr(13)
text1=ad$
if I run this same program on two of my PC's both with VB6 and SP6 one of them performs the CR and LF whilst the other displays ||, I do not understand why there is any difference, I can see that it is not the VB but must be some language setting on the PC's but as far as I can see they are identical, it is not only the text box if I set a break point on the text1 line and put my cursor on Ad$ I still get the same results as would be displayed in their text boxes, ie one of them shows me that the value for Ad$="||". but the other Ad$="".

What is the OS for the laptop? I know certain OS's (like Linux) interpret CR's differently than Microsoft OS's do.

Lf then Cr is entirely different from Cr then Lf.
The VB6 instrinsic function MsgBox interprets Lf, Cr, CrLf, or LfCr all as "newline" symbols.
A multiline instrinsic Textbox control interprets CrLf as newline, but has no idea what you mean by LfCr and thus will display a pair of "default" symbols, which look something like "|" in many fonts. CrLf will give a similar pair of default symbols in a Textbox where Multiline = False.
In your second post here you use Chr(10) & Chr(13), which yields a variant string LfCr.
This serves once again to show why there is nothing 'leet about using the Chr/Chr$ functions where they aren't warranted and why the practice should be avoided.
When you want a newline in VB6 you should be using the intrinsic constant vbNewLine (which in Windows VB/VBA is equal to the constant vbCrLf). That's why it exists, to help programmers avoid such errors and to help others understand the original programmer's intent.
One is sometimes reminded of Obi Wan's advice to young Luke: "Dude, stop fighting it.

It's also likely it's a font issue. Make sure that the same font (and version of the font) is loaded on both computers.
