Subject Can a variable have local scope?
Date Thu, 12 Jul 2001 23:43:37 GMT
hi

Can I have a variable with local scope in velocity? I wrote a macro that
calls itself again and again and I have defined a variable in that macro and
set it to 1. Each time the macro calls itself, the variable is incremented
by 1. but, when the control comes back to the calling macro, the old value
is not retained and instead the new value is being used. (The application
that I am using here is like printing a binary tree)

Please help me in this regard
