Changing dimstyles unwanted

Can anyone alter this lisp so that it does not overwrite current dimstyle values? When it is used to change the scale of a drawing, it changes certain properties of the drawings dimstyles. It seems to mainly effect the colors 0f ARCH48 and ARCH96 dim styles (although it doesn't seem to be extremely consistant!). Is there something in here that changes dimstyles to some standard within the lisp? any help is appreciated. thanks in advance.

Comment out following lines:

I think I understand... I replace all of the specified text with the ";" ? is this correct. This works fine in not altering the existing dimstyle, but now it does not specify the correct dimstyle as current (1/8" scale = Arch96 style for example). Can this function be kept, but just not change arch96 from its definitions within the drawing? basically it changes the colors from always red to by layer, which is not wanted. Make sense?

thanks again for the help.

adam,
try commenting this one. Seems to be only variable that has 'Red' (4) bit. Make it like:

;(setvar "dimclrt" 4)
