how do make a new paremeter eqaul to the 7th character of nums_type.

${type} = b

I would not use type as a variable name since there is a type command. And using typeset without any options only makes sense inside a function. But here is one way to get that character:
Code:
#! /usr/bin/ksh

x="asdfghbqwerty"
drop6=${x#??????}
y=${drop6%${drop6#?}}

echo $y
exit 0

There are other ways, but I like this since it does not invoke any external programs.

I personaly like sed and its placeholders - although it's an external program Smilie

Would look like:

#!/usr/bin/ksh
x="asdfghbqwerty"
y=`echo $x| sed "s/\(......\)\(.\)\(.*\)/\2/"`
echo $y
