I have a very huge while wend loop in my excel vba : I have a very huge while wend loop in my excel vba

previous in the code I set a variable (strMode) to true or false

if it is false then in my while condition I want to set

while var1 + var1previous > 1 

and if it is true

while var1 + var1previous > 1 or var1previous + var1 > 1

How can I do that, if I don't what to "double" the while wend code, for my if statement?
