st: Problem with local variable
Oops, sorry, the last mail had a wrong title...
In a loop, I use a local integer variable x that goes from 1 to k. In
some commands within the loop, I need using the value x-1. I succeed
in creating another local variable : local x1=`x'-1. But I wonder why
it didn't work when I used directly ``x'-1'. What is wrong in this
