is it better form to do this:
while($exlen > 0){$indent=$indent." ";$exlen=$exlen-1;}
or this
while($exlen){$indent=$indent." ";$exlen=$exlen-1;}
(or is the second one even going to work?)
2nd question:
why do sometimes I have to call a subroutine with an ampersand
&subroutine();
and other times can just say the name of the subroutine
subroutine;
??
Thanks for help, advice, etc!
