Another way with sed (first and last can't be special chars) :
Code:
str="abcdpqracdpqaserd"
first=a
last=d
substr=$(echo "$str"| sed -n "s/^[^$first]*\($first[^$last]*$last\).*/\1/p")

Code:
$ sh -x substr.sh
+ str=abcdpqracdpqaserd
+ first=a
+ last=d
++ echo abcdpqracdpqaserd
++ sed 's/^[^a]*\(a[^d]*d\).*/\1/p'
+ substr=abcd
+ echo abcd
abcd
$
