HoldTemporary may do the trick for you. http://library.wolfram.com/infocenter/MathSource/705/ Hold or HoldForm might also do it: p = a*x + b*x; p + HoldForm[Subscript[p, D]] Bobby From: Bruce W. Colletti (bcolletti at compuserve.com) To: mathgroup at smc.vnet.net Subject: [mg46800] Substitution This is the only article in this thread View: Original Format How to make the variable Subscript[p,D] wholly unrelated to variable p? For instance, the notebook... p = a x + b x; p + Subscript[p,D] ...produces a x + b x + Subscript[ax+bx,D]. But I want p + Subscript[p,D] and thereafter, to freely use Subscript[p,D] without it being affected by the p-value. Symbolizing Subscript[p,D] didn't work. Thankx. Bruce
