Question

I want to transform the following c code to TCL.

int a[10],b[10];
int n=20

for (i=1,j=1; i<=n; i+=2,j++)
{
  b[j]=a[i];
}

I need to change this for loop to TCL, I don’t want to use the foreach feature in TCL…
Does TCL for loop structure allow two loop variables???

Have you seen the discussion here:

  set n 6
  for {
              set  i     1
              set  j     1
          } {
              $i < $n
          } {
              incr i
              incr j
          } {
              puts "$i $j"
   }
