Adding A Background Mask & Feet Squared To A LISP Routine

[wilsons3774183]

Hi,

This is my first post here and was hoping i could get some help or guidance to modify a lisp routine.
Based on Lee Macs great routine A2F (Area To Field) with some modifications done at a previous company, i am looking at adding a background mask for the text and if possible also adding feet squared to the lisp routine so that the calculation for the area will show as both meters squared and feet squared.
I am very limited to LISP coding and would really appreciate any help with this.
