Here's a quick copy/paste method to show it working in action -- like
David said, make sure scr_ysize or ysize is set large enough on your
widget_label.
mylabel='1stline'+string(byte(13))+'2ndline'+string(10b)+'3r dline'
dummy = widget_base(xsize=150, ysize=100)
lbl = widget_label(dummy, value=mylabel, scr_ysize=50)
widget_control, dummy, /realize
Cheers,

Wow. That's the last time I say "not possible". :-)
Just be sure you give your widget enough Y size so
you can see the label, if you try this at home.
I'll probably have an article about this later today. :-)
Cheers,
David

The label widget does not seem to understand embedded formatting.
However, I found the string() function very helpful. The following
code works for me.:)
mylabel="1stline"+string(byte(13))+"2ndline"
widget_control, label_id, set_value=mylabel
cheers,
