I believe that the line that says
filename=${filename:?"missing."}
needs to instead read
filename=${filename:?"filename missing."}
to result in the messge printed two lines later:
highest: line 2: filename: filename missing.
AUTHOR: The correct change is to fix the error message:
highest: line 2: filename: missing.
Thanks for reporting this. FYI, ksh93m+ gets it wrong, alas:
$ cat foo.ksh
#! /home/arnold/bin/ksh93
filename=$1
filename=${filename:?"missing"}
$ foo.ksh a
$ foo.ksh
./foo.ksh: line 4: missing: missing
Bash gets it right:
$ bash foo.ksh
foo.ksh: line 4: filename: missing

There is:
DIRSTACK="$dirname DIRSTACK"
that doesn't replace DIRSTACK (between double quotes) by its value.
instead of:
DIRSTACK="$dirname $DIRSTACK"
that replace DIRSTACK (between double quotes) by its value.
