Re: st: Manual class programming example

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.
