Changing space-formatted tables to tabs

[Jay Schille]

I've got some weather information tables from the Web that are 
formatted like so:
Seattle                    60   40   61  /  10   30   100
Tacoma                  58   42   60  /  10   40   100
Mercer Island          59   41   59  /  10   30   100
Woodinville              61   43   62  /  20   20   100
etc.

The records are separated by chr(13), but all the other gaps are empty spaces.
Is there any easy way to replace the gaps with tabs or some other 
single delimiter, no matter how many spaces comprise the gap?

Something better than this:
local oWeatherTable 	/* the table above */
local x
x=1
loop
if array(oWeatherTable, x, chr(13)) contains "           ",
	array(oWeatherTable, x, chr(13))=replace(array(oWeatherTable, 
x, chr(13)), "           ", chr(9)
x=x+1
and so on, which can get pretty tedious covering all the 
possibilities of gap size.

Any simplification of this process will be much appreciated.
