I can't talk for [t]csh. In bourne compatible shells, set -x. Me personally, I search for keywords like "option" or "set" in the respective man pages.


If your "code is written exactly as it is in post #1", how come the error msg in post#3 is different?

I am not sure why it adds spaces. The only coding I have changed is in prog3, I changed the spacing in some areas, and the results are now

Code:
gaben:~/CS307> more prog3
more prog3
#
set pwrs=(00000000)
@ pwrs[1]=1
@ next=2
while($next<9)
   @ last=$next+1
   @ pwrs[$next]=$pwrs[$last]*2
   @ next=$next+1
end


@ count=1
while($count<=8)
   echo $pwrs[$count]
   @ count=$count+1
end
gaben:~/CS307> ./prog3
./prog3
@: Badly formed number.
gaben:~/CS307>
