vba - Excel macro - divide procedure into more subs -

my procedure has become large , won't run anymore. i've redesigned code in mind, need current code , running before start editing. i've looked online , need split procedure subs , call them, none explain or show how this.

thanks!

sub sub1()     ' code... end sub  sub sub2()     ' code... end sub  sub main()     sub1     sub2 end sub
