Usage Recommendation
use it, but don't rely on it

<NOBR> prevents a carriage return from occurring. For example, the following code produces a nonsense poem of one long line:

<NOBR>
Twisting and turning, spinning and shouting, hissing and roaring,
fearing and jeering, stomping and yelling, running and jumping, 
peeling and dicing, cooking and weighing, costing and pricing, 
eating and drinking, all in a day's work.
</NOBR>

produces
Twisting and turning, spinning and shouting, hissing and roaring, fearing and jeering, stomping and yelling, running and jumping, peeling and dicing, cooking and weighing, costing and pricing, eating and drinking, all in a day's work.
<NOBR> is most useful for making the page layout more attractive by disallowing breaks inside logical groups of symbols and words. The poem quoted above breaks in appropriate places if each phrase is surrounded by <NOBR>:

<NOBR>Twisting and turning,</NOBR> 
<NOBR>spinning and shouting,</NOBR> 
<NOBR>hissing and roaring,</NOBR> 
<NOBR>fearing and jeering,</NOBR> 
<NOBR>stomping and yelling,</NOBR> 
<NOBR>running and jumping,</NOBR> 
<NOBR>peeling and dicing,</NOBR> 
<NOBR>cooking and weighing,</NOBR> 
<NOBR>costing and pricing,</NOBR> 
<NOBR>eating and drinking,</NOBR> 
<NOBR>all in a day's work.</NOBR>

produces
Twisting and turning, spinning and shouting, hissing and roaring, fearing and jeering, stomping and yelling, running and jumping, peeling and dicing, cooking and weighing, costing and pricing, eating and drinking, all in a day's work.
