\framebox
.........
`\framebox(width,height)[position]{...}'
The `\framebox' command is exactly the same as the `\makebox'
command, except that it puts a frame around the outside of the box that
it creates.
The `framebox' command produces a rule of thickness `\fboxrule', and
leaves a space `\fboxsep' between the rule and the contents of the box.
