cant use sed or awk

i cant use sed or awk so i was thinking of something like using head and tail to split up the file but it aint working quite right, plus it doesnt fit with the notion of adding any argument

head -$N file > f1
tail -$N file > f2
cat f1 #need to echo and cat $1 here# f2 > newfile
mv! newfile file #needs to retain file name

could n be subbed for a variable that halfs the wc -l or something.

if anyone can shed some differing light upon this idea i wud b eternally grateful

NAME
WidgetDemo() - create a standard widget demonstration window. SYNOPSIS
use WidgetDemo; my $TOP = $MW->WidgetDemo( -name => $demo, -text => 'Learn how to write a widget demonstration!', -title => 'WidgetDemo Demonstration', -iconname => 'WidgetDemo', -geometry_manager => 'grid', -font => $FONT, ); DESCRIPTION
This constructor builds a standard widget demonstration window, composed of three frames. The top frame contains descriptive demonstration text. The bottom frame contains the "Dismiss" and "See Code" buttons. The middle frame is demonstration container, which came be managed by either the pack or grid geometry manager. The -text attribute is supplied to a Label widget, which is left-adjusted with -wraplength set to 4 inches. If you require different specifications then pass an array to -text; the first element is the text string and the remaining array elements are standard Label widget attributes - WidgetDemo will rearrange things as required.. -text => ['Hello World!', qw/-wraplength 6i/], AUTHOR
