Are you skipping the initial periods (. prompts) correctly, but
incorrectly typing in the numbers (1. and 2. and 3.) after issuing the
program command? You would not type the numbers (2. and 3.) in the
following:
. forv i=1/2 {
  2. di `i'
  3. }
and the same principle applies here. See -help classman- for correct syntax.
