one question in variable
in the syntax ,we normally use :
if { $cjj == 1} {
xxxx
}
I have a question here
sometimes I forget to define this variable cjj,is there any method I can use to make it work in this way:
evulate wether there is a varable cjj,if not define one
such as :
if $cjj exist ,else set cjj x
thanks in advance
