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

bottom, in the script

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.
