Multiply variables
I have no idea about programming, just know some simple html
 and I need to get to somebody that can help me with creating the application (?) that will multiply 2 varibales and given price (height x lenght) x $$$.PLEASE HELP! edit by bakunin: Anita, as much as we appreciate your question, i have to tell you that you posted it to the wrong forum part. This part, as the name should suggest, is a "Forum Support Area for Unregistered Users & Account Problems" an definitely not for a scripting problem such as yours. I will transfer your post to where it belongs, but i would like to ask you to place your postings right from now on. Last edited by bakunin; 05-06-2008 at 05:36 AM.

You can do that with a little script like the one i have written for you. It will start over and wait for input as long as Input is non-zero. If it is it will terminate.
Note that the script makes no efforts to validate the input - entering a string or another nonsensical value instead of an (integer) number will cause a error message by the shell. Code:
#! /bin/ksh
typeset -i iLen=0
typeset -i iHgt=0
typeset -i iPrc=0
while : ; do
read iLen?"Enter length: "
if [ $iLen -le 0 ] ; then
exit 0
fi
read iHgt?"Enter height: "
if [ $iHgt -le 0 ] ; then
exit 0
fi
read iPrc?"Enter price : "
if [ $iPrc -le 0 ] ; then
exit 0
fi
print - "\nProduct (Length x Height x Price) is: $(( iLen * iHgt * iPrc ))"
print - "\n\n"
done
exit 0
I hope this helps. bakunin

And in ksh93 syntax:
Code:
#!/bin/ksh93
integer iLen=0
integer iHgt=0
integer iPrc=0
while : ; do
read iLen?"Enter length: "
(( $iLen <= 0 )) && exit 0
read iHgt?"Enter height: "
(( $iHgt <= 0 )) && exit 0
read iPrc?"Enter price : "
(( $iPrc <= 0 )) && exit 0
printf "\nProduct (Length x Height x Price) is: %d\n\n" $(( iLen * iHgt * iPrc ))
done
exit 0
