i am wondering if it is possible to have a macro that opens the vbe for the active worksheet, finds the code line 
.Top = xxx
and replaces it with 
.Top = .Top.Value - 9
or something similar.

what i am trying to accomplish is have a macro permanently change the position and height of the active worksheet. when i run the macro it should go into the "This Workbook" excel object module for the active workbook, find the specific line of code (no matter its location in the code), and subtract "9" from its current value

thanks
