Sorry to be blunt, but you first need to learn the basics of shell scripting, only then you can expect to get something - anything - running.

That's what i figured.

Code:

/bin/ksh

shebang missing

Code:

group=hasasvmi
date1=09/29/2016
n=1
|{
read "$group"
read "$date1"
read "$n"

This will not only not work, it is also superfluous. If you use a pipeline you connect processes: process1 | process2 means: start process1 and whatever comes out of its stdout output channel (the part usually printed on screen) put into process2s stdin (normally connected to the keyboard). Since variable=value is not a process, there will be no output and hence nothing to feed your pipe.

Code:

WHILE
[...]
DO
[...]
ELSE
[...]
DONE

I have told you already that capitalisation matters and that keywords are not "WHILE", but "while". What do you expect the shell to do if you write gibberish (^=unknown commands/keywords)?

My suggestion is to get some introductory book on shell programming and start reading it. You cannot expect to guess your way to some working code without knowing (obviously) neither UNIX nor shell and while we are willing to answer your questions we will not write complete scripts for you. Anything less than that, i suppose, would not suffice to get working code, though.

I hope this helps.
