[MacPerl] truncating

[Rick <RGabrie1@nycap.rr.com>]

how do i truncate something?  say...a variable or an element in an
array...  i tried 

truncate($cm[1][0],300);

and it definately did not truncate the element.  does the number mean 300
bytes or characters or what?  the help file is very vague.  how does this
work exactly?  please help.  thanx.
