I know very little about unix. How can I make a menu item return to the previous menu if the process is aborted? Right now it takes me all the way out to a % prompt. I am on Unix Sco 5.0.5. Other than that I don't know too much.

If by an abort, you mean a Ctrl-C, try adding the following early in your script:

stty intr "^C

Sorry - should have added that the ^C is generated using a ctrl-Vctrl-C sequence.

i use a telnet program called putty. I right click and go to interrupt process. I don't use control-C

Can you post your "menu" script?
If the menu prompts for a selection, then does an "exec" of another script, the menu script can't wait around for the secondary script to end. On the other hand, if you keep the user in a loop within the menu, and do NOT "exec" the task script, the menu should still be running when the task script ends.

Code: 
#delimdd.pm

  echo "\nEnter the password: \n"
                read pword
cd /usr/ias/stories
word $pword.lst;

cd /usr/ias/misc/delim
vi delim"$pword";

chmod 777 delim"$pword"
delim"$pword" < /usr/ias/stories/"$pword".lst > /tmp/"$pword".1;

cd /tmp
more "$pword".1;

        isql soils - <<TEXTA
delete from iastun
where ipassword = "$pword";
load from $pword.1
insert into iastun;
TEXTA
cd /usr/ias/bin
sperform -s iastun;

  echo "\nEnter the password: \n"
                read pword
cd /usr/ias/stories
word $pword.lst;

cd /usr/ias/misc/delim
cp delimht delim"$pword";
vi delim"$pword";

chmod 777 delim"$pword"
delim"$pword" < /usr/ias/stories/"$pword".lst > /tmp/"$pword".1;

cd /tmp
more "$pword".1;

        isql soils - <<TEXTA
delete from iastun

load from $pword.1
insert into iastun;
TEXTA
cd /usr/ias/bin
sperform -s iastun

So, why posting in an unix forum for IT professionals ?

Because our unix person quit, and I must do this until we get a replacement. Sorry for offending you.

The code for handling interrupts is there - see trap statements that were commented out for some reason...

# this code made some weird messages in SCO Xenix
# CDB 88.05.02
# trap "echo \007" 2
#trap "echo shell aborted; exit 1" 3

Uncomment the two 'trap' lines and see what happens. If you get the so called weird messages, I would like to know what they are... (uncomment: edit the script and remove the '#' characters before the word trap)

Telnet "Interrupt Process" command or ctrl-C in the shell session act somewhat similar - a signal called SIGINT is sent to the process that is running in your login session. It is just a difference of who generates the signal - the shell or the telnet program.

With trap you can choose to ignore or act upon reception of a specific signal. By commenting the 'trap' lines you get the default action - all running processes are interrupted and your shell session returns to the shell prompt...
