[texhax] TeX query 5: \hsize and \settabs

[Paul Stanley]

Hi folks,
I've been playing with the `\settabs' macro and have made the 
following observations (with a little help from a sighted friend):

* All columns are left-aligned by default.

* The `\settabs' structure ( `{\hsize ... \settabs ... }' ) is 
left-aligned on the page by default.

* The `\hsize' value determines the length of the gap between the 
left-most edge of the left column and the left-most edge of the right 
column for each pair of columns.. So, the `\hsize' value in a table 
with 4 columns will apply to columns one and two, two and three, and 
three and four. The gaps between the points in all pairings is the same length.

* A `0' value assigned to `\hsize' will left align all columns and 
place them on top of each other over the left-most column in the table.

* A positive value of `\hsize' will measure the two points in the 
column pairings in the order the columns appear in the source.

* A negative value of `\hsize' will produce a mirror of the output 
produced by its positive inverse.

Other than that, please feel free to point out any errors or fill in 
the gaps in above notes.

Many thanks,
Paul
