Re: Enter "NewLine"Your code seems to work the way you thought it would. I just had to expand the height of the rows to have it displayed.

names default to here(1);
dt =
// Open Data Table: Big Class.jmp
// → Data Table( "Big Class" )
Open( "$SAMPLE_DATA/Big Class.jmp" );
:name[1] = "A\!nB"
Re: Enter "NewLine"and is this possible without JSL, just by typing?
Re: Enter "NewLine"Here's one way, which is admittedly a bit of a hack:
- Open a new script window
- Hit enter
- Shift+up arrow to select that new line/carriage return
- Copy to clipboard, Ctrl+c
- Back to data table, enter first line, then Ctrl+v to paste, then enter second line.

Re: Enter "NewLine"I tried the method to enter and evaluate expressions to a literal value directly, but it only works for numeric expressions.
Re: Enter "NewLine"Nice trick - thanks 
Enter "NewLine"I want to split a string in a character column into two lines - by adding a newline.
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
name[1] = "A\!nB"
Can I do this directly when editing the cell - Alt + Enter doesn't seem to be right?
Data Blending and CleanupResponse: Enter "NewLine"You can delete; first, then type another; and then press enter
