If your whole program is 900 lines without a subroutine then you have 
more problems than just tabbing...really, a program this big should have 
many functions to divide up the work. Looking for a workaround for poor 
program structure is not a good solution in the long run; fixing the 
program structure so it is workable is a better idea.

As a practical matter, many editors allow you to select and indent a 
block, including TextPad and Eclipse, the two editors I usually use.
