I am back again. I had a basic inquiry and your help got me started. My problem is as follows:
*I have just started to work through 2Htdp (i.e. the second edition) that you had guided me to. Having gone through the prologue I am now on the second chapter, "Fixed-size data." But have got stuck almost at the start. I have successfully done the first two exercises but have hit a road block on exercise 3 (section 2.1.3 "Mixing it up"). I do not know what instruction to use to insert or extract a letter from the ith position. I think I am doing something wrong when trying to look up things in Helpdesk. Please help.* * * *Saad * On Fri, Apr 27, 2012 at 8:32 PM, Danny Yoo <d...@cs.wpi.edu> wrote: > On Fri, Apr 27, 2012 at 11:27 AM, saad bashir <bashir.s...@gmail.com> > wrote: > > Your help was great.
