howto define variable in .onInit and use it in pages

[Masternoob]

is there a way to define a variable in .onInit and then use it in all pages?

i am trying to do this because i need to change the pages dynamically with this parameter...

i already tried !define variable... it works but the problem is that you can't change this value at runtime...or at least i haven't found a way to do so

thx for your help

EDIT: Ok i am stupid, you have to declare the variables before the pages *facepalm*

Use 'Var' to make a variable. Use /GLOBAL (ex 'Var /GLOBAL MyVar') if used in a section or function.
